From humble immigrant origins, he rose to a prominence, which few can match. Best remembered as an eminent entrepreneur, social reformer, political activist, philanthropist, community leader, and educationist, he died at the age of 87 in Beijing on August 12 1961 and was accorded a national funeral by the Chinese Government for his contribution to the society.3.CampusThe University has a total campus area of over 538 hectares. The Main Campus on Xiamen Island has an area of 167 hectares; the Zhangzhou Campus is 171 hectares in area; and the Jimei Campus has an area of 200 hectares. Xiamen University's main campus is located in Siming District, southwestern Xiamen. Located at the foot of the green mountains, facing the blue ocean and surrounded by Xiamen bay. With green hills behind and the sea close by, the three campuses are set amidst delightful scenery and are generally recognised as one of the most beautiful campuses in China. the university also has campuses at Jimei and Zhangzhou. The Xiamen campus of Xiamen University is remarked as "the most beautiful campus in China". It is at the foot of mountain and beside the seashore, with two lakes within the campus and trees, flowers and green lawn everywhere. The beautiful and peaceful environment is very good for self-reflection.3.1 The gate of Xiamen University.It was the largest university gate in China in that year. The whole building was made of rock. It looks like a bird which opens its wing to fly in the sky. It means the university will make progress and have a bright future. And its three arches signify Xiamen University's pardon and opening. The four words "Xiamen University" was written by a famous writer-Luxun. The whole gate expresses some Xiamen University’s main specialties.3.2 Jiannan Auditorium ComplexThere is a famous hall named "Jiannan assembly hall". This building style is full of classical and modern art. Mr. Chen kah kee personally participate in the hall’s design and project supervision. It was built in 1952, and finished in 1954. The hall's construction is wonderful article excelling nature. It combines ancient and modern, Chinese and Western, and it become a particular building learning widely from others' strong points. Five halls are arranged appearing camber and they are facing the ocean. This building is also the symol in Xiamen.It can hold 4000 students at the same time. It's not only big, but also grandness.3.3 Lotus TunnelThis is also one of the symol buildings in the university. It is 1455m long. Among them, pedestrian tunnel is 1015 meters long, 8m wide and 5.1m high. In the Xiamen University, all the studentsknows Lotus tunnel, which is named Graffiti tunnel by our students now. It had been clean and clear. There were rows of fluorescent lamps. The locomotive was forbidden in the tunnel. Even if we walked in the tunnel at deep night, we can also feel safe. Later, the fluorescent lamps went out and they were changed by energy-saving lamps that there were few bright spots. One day many pictures dropped from the skies in the white wall.In this tunnel, students can draw pictures, or write the pop words. It was design by the students. Some of them are about love, some of them are about friendship. This "chicken tracks" attract others attention and become the symbol of this university.3.4 Economics ComplexThe complex of School of Economics was located near the West Gate of Xiamen Campus. It consists of five buildings, which are all connected with piazzas and inlaid with gardens. Each teacher can expect to have an office of different size in the building. There are also sports rooms especially equipped for teachers.3.5 LibraryThe XMU's library is set up in 1921. Now it has one main library, two medical libraries, three specialty libraries and seven reference rooms. It occupies 6.68 million square meters. It is a five star library. In 2005, there had been 4,090 thousands books. The books are keeping in library by the numbers and the association about Southeast Asia and Taiwan is so distinctive. Now the perfect checking system can be handled in internet.The library has five floors. There is full room for students to read and study. There are always most students in every floor and in the time close to exam there will be no room if you get late. We can see a university's good atmosphere in there.4.FutureNow, Xiamen University has four campuses. They are cadre campus, zhangzhou campus, haiyun campus and xiang'an campus. Among them the xiang'an campus is being put up. Every campus has its good hardware capacities to give students and teachers rich sources. They are linked tightly very much. Different grades' students and those students who learn different majors will live in different campus. And every campus' choosing is upon different students' features. Xiamen University, thispolicy makes full use of its sources and let its students have their suitable learning and living atmosphere.Xiamen University is making great strides towards its goal of "building a high-level university well-known both at home and abroad." From the time it was set up, more and more talents go out from this university. Under its special policy, professional teaching team and good studying atmosphere, it must will give China and even our human beings more and more fresh blood. Following the school motto "Pursue Excellence, Strive for Perfection", Xiamen University will have a bright future. The university will provide more undergraduates and graduates for the country to do what they can do. And there will be more brand new technology from them. It was like a new beautiful word there.For me, I also want to say. May be, today, I'm studying in Shenda not Xiada, but I can also use the motto from this university in order to improve myself. I have confidence that I can do better than those Xiada’s students and I must accomplish it.Xiamen University is really a good place that has good environment and most top talents. But I want to say, being young, knowledgeable and self-motivated, they will become the leading economists and economics educators of tomorrow. No mater where we study now, we can also make big progress。

Naming Inorganic CompoundsIntroduction：1.10 million known chemical substances.Need to establish a set of rules leading to informative, systematic name for each substance.2.Nomenclature: basic rules for naming simple compounds (organic compounds,inorganic compounds)Contents of current section：1.Preparatory materials（names of common elements in the periodic table)；2.Ionic compounds (cations, anions,compounds)；3.Acids；4.Molecular compounds Common Elements：Ac-Actinium锕, Ag-Silver, Al-Aluminum, Ar-Argon, As-Arsenic, Au-Gold, B-Boron, Ba-Barium, Be-Beryllium, Bi-Bismuth, Br-Bromine, C-Carbon, Ca-Calcium, Cd-Cadmium, Ce-Cerium铈, Cl-Chlorine, Co-Cobalt, Cr-Chromium, Cs-Cesium铯, Cu-Copper, F-Fluorine, Fe-Iron,Ga-Gallium镓, Ge-Germanium锗, H-Hydrogen, He-Helium, Hg-Mercury, I-Iodine, In-Indium, Ir-Iridium铱, K-Potassium, Kr-Krypton, La-Lanthanum镧, Li-Lithium, Mg-Magnesium, Mn-Manganese, Mo-Molybdenum钼, N-Nitrogen, Na-Sodium, Nb-Niobium铌, Nd-Neodymium钕, Ne-Neon, Ni-Nickel, O-Oxygen, Os-Osmium锇, P-Phosphorus, Pb- Lead, Pd-Palladium钯, Po-Polonium 钋,Pt-Platinum, Pu-Plutonium钚, Ra-Radium, Rb-Rubidium铷, Re-Rhenium铼, Rn-Radon氡, Ru-Ruthenium钌, S-Sulfur, Sb-Antimony锑, Sc-Scandium钪, Se-Selenium硒, Si-Silicon, Sm-Samarium钐, Sn-Tin,Sr-Strontium锶, Ta-Tantalum钽, Te-Tellurium, Ti-Titanium, Tl-Thallium, U-Uranium, V-Vanadium钒，W-Tungsten, Xe-Xenon, Y-Yttrium钇, Zn-Zinc, Zr-Zirconium锆Ionic compoundsGeneral rule :The names of ionic compounds are based on the names of the ions of which they are composed. The positive ion (cation) is always named first and listed first in writing the formula for the compound. The negative ion (anion) is named and written last.Eg.：NaCl (sodium chloride)Naming cationsMonatomic ions (take the name of the element itself)Zn2+ (zinc ion), Al3+ (aluminum ion)Note: for an element (especially transition metals) with more than 1 positive ion, the positive charge of the ion is indicated by a Roman numeral in parentheses following the name of the metal:Fe2+ --- iron (II) ion, Cu+ ---copper (I) ionIf unsure, use the Roman numeral designation of charges aspart of the name.Naming cationsNote: A widely used older method to distinguish between two differently charged ions of a metal is to apply the ending –ous for the lower charged ions or -ic for the higher charged ions, respectively. They are added to the root of the Latin name of the element.Eg.：Fe2+ (ferrous ion), Cu+ (cuprous ion)Fe3+ (ferric ions), Cu2+ (cupric ion)Naming cationsPolyatomic cations: Groups of atoms with a positive charge. NH4+--- ammonium ion Hg22+ ---mercury (I) ion or mercurous ionNote: Hg2+ ---mercury (II) ion, or mercuric ionCommon ions：Cations: ammonium, cesium, copper(I) or cuprous, hydrogen, lithium, potassium, silver,sodium.(+1 ions); barium, cadmium, calcium, cobalt(II) or cobaltous, copper(II) or cupric,iron(II) or ferrous, lead(II) or plumbous,magnesium, manganese(II) or manganous,mercury(I) or mercurous, mercury(II) or mercuric, nickel, strontium, tin(II) or stannous, zinc.(2+ ions); aluminum, chromium(III) or chromic, iron(III) or ferric.(3+ ions)Monatomic anions (named by dropping the ending of the name of the element and adding the ending -ide ):Naming anionsPolyatomic anionsNote: only a few polyatomic anions end in -ide:OH- hydroxide ion, CN- cyanide ion O22- peroxide ion, N3- azide ion Naming anionsOxyanions(polyatomic and oxygen-containing):when an element forms two oxyanions, the name of the one containing more oxygen ends in-ate; the name of the one with less oxygen ends in -ite:Eg.：NO2- nitrite ion, SO32- sulfite ion ,NO3- nitrate ion, SO42-sulfate ionNote: when the series of anions of a given element extends to three or four members,prefixes are also employed. The prefix hypo-indicates less oxygen, and per- more oxygen:Eg: ClO-hypochlorite ion, ClO2-chlorite ion ClO3-chlorate ion, ClO4- perchlorate ion chlor---root of chlorineNaming anionsPractice: selenate ion (?); selenite ion (?) perbromate (?) , hypobromite (?)Note: exceptions to rules: permanganate ion is MnO4-, manganate ion is MnO42-. ferrate-(or perferrate) FeO4-，chromate CrO42-, dichromate Cr2O72-Naming anionsPolyatomic anions with hydrogen ionsThese ions are named by prefixing the word hydrogen or dihydrogen, as appropriate,to the name of the hydrogen-free anion.Alternative way is to use the prefix bi-:Eg.：HCO3- hydrogen carbonate (or bicarbonate ) ion; HSO4-hydrogen sulfate ( or bisulfate) ion; H2PO4-dihydrogen phosphate ionCommon ionsAnions: acetate, azide, bromide, chlorate,chloride, cyanide, dihydrogen phosphate,fluoride, hydride, hydrogen carbonate or bicarbonate, hydrogen sulfate or bisulfate, hydroxide, iodide, nitrate, nitrite, perchlorate, permanganate, thiocyanate, cyanate. (1- ions);carbonate, chromate, dichromate, ferrate,hydrogen phosphate, oxide, peroxide, sulfate,sulfide, sulfite, thiosulfate.(2- ions); nitride,phosphate, phosphide. (3- ions). Naming ionic compoundsWrite the formulas for ionic compounds by combining the names of cations and anions:barium bromide- BaBr2copper(II) nitrate or cupric nitrate- Cu(NO3)2aluminum oxide-Al2O3mercury(I) chloride or mercurous chlorideHg2Cl2ferric oxide, Fe2O3Practice : Name the following compounds:(a)K2SO4；(b) Ba(OH)2；(c) FeCl3 (d) NH4Cl；(e) Cr2O3；(f)Co(NO3)2Write the chemical formulas for the following compounds: (a)calcium carbonate; (b)sodium fluoride; (c) iron(II) perchlorate; (d)magnesium sulfate; (e) silver sulfide; (f) lead nitrate.Naming AcidsAn acid here is defined as a substance whose molecules yield hydrogen ions (H+) when dissolved in water.Rule : The name of an non-oxyacid is related to the name of the anion. Anions with the ending -ide associate with acids having hydro- prefix and an -ic ending:Eg:Chloride (Cl-) to hydrochloric acid (HCl) sulfide (S2-) to hydrosulfuric acid (H2S)Note: only water solution of HCl is called hydrochloric acid, the pure compound is called hydrogen chloride.Naming the acidsFor acids derived from oxyanions (oxyacids)Rule: If the anion has an –ate (-ite) ending,the corresponding acid is given an –ic (-ous) ending. Prefixes are retained:Naming the acidsExercisesName the following acids:(a) HCN, HSCN; (b) HNO3, HNO2 (c) H2SO4 (d) H2SO3 Give the chemical formulas for(a)hydrobromic acid; (b) phosphoric acid.Naming molecular compoundsRule:The procedures for naming binary (two-element) molecular compounds are similar to those for naming ionic compounds. The element with the positive nature is named first and also appears first in the chemical formula. The second element is named with an–ide ending.Eg.:HCl hydrogen chlorideNaming molecular compoundsPrefixes are used in differentiating several binary compounds formed between nonmetals.Eg:CO -carbon monoxide CO2-carbon dioxideMeaning of the Greek prefixes:mono- (1); di- (2); tri-(3); tetra-(4); penta-(5);hexa-(6); hepta-(7); octa-(8); nona-(9); deca-(10)Naming molecular compoundsNote: when the prefix ends in a or o and the name of the anion begins with a vowel (such as oxide), the a or o is often dropped. The prefix mono- is usually omitted for the first-named element.Eg.:Cl2O - dichlorine monoxide; NF3- nitrogen trifluoride; N2O4- dinitrogen tetroxide; P4S10- tetraphosphorus decasulfide; ExercisesName the following compounds:(a) SO2; (b)PCl5; (c)N2O3Give the chemical formula for(a) silicon tetrabromide (b) disulfur dichlorideExercises for ReviewSodium fluoride, magnesium bromide,hydrogen iodide, sodium azide , calcium phosphide,copper(I) chloride, potassium azide,manganese (IV) oxideK2SO3, Ca(MnO4)2 , Ba3(PO4)2, H3PO4 ,H2SO4 ,HNO3 , ZnO , BaO2 ,FeO ,CuSO4•5H2O , Mn3(PO4)2 Metaphosphoric acid, phosphoric acid,hypophosphorous acid, phosphorous acid,(hypo)phosphite, (meta)phosphate ammonium acetate, perbromic acid , potassium nitrite, sodium peroxide , ammonium dichromate ,sodium carbonate , silver nitrate , aluminum acetate, hydrosulfuric acid, sulfurous acid, perferric acid, perferrate ion, hypoiodite ion,iodic acid , chlorous acid, hydrochloric acidB2O3, SiO2, PCl3,SiCl4, BrF3, IBr,N2S5, PCl3, SiS, S4N2 Exercise: learning for useWhen ammonium thiocyanate and barium hydroxide octahydrate are mixed at room temperature,an endothermic reaction occurs.(write the chemical equation). As a result of this reaction, the temperature of the system drops from about 20°C to -9 °C.The reaction of powdered aluminum with ferric oxide (known as the thermite reaction) is highly exothermic. Once started, the reaction proceeds vigorously to form aluminum oxide and molten iron. (write the chemical equation)Nomenclature for Organic Compounds and GroupsWhy Do We Need a Separate Set of Rules?Examine some typical organic compounds (Name these using typical covalent rules)CH4:Carbon tetrahydride C2H6:Dicarbon hexahydride That wasn’t so bad, right?How about these:C4H10:Tetracarbon decahydride C5H12:Pentacarbon hydride See my point?Memorizing too many prefixes for large numbers Isomers：If that’s not enough, how about this one:Rules•Identify the longest unbranched chain of carbons •Name it as normal•Identify the branch•Name it but give it a “–yl”suffix•Put the names of all branches first, then put name of longest chain•Put the number of the carbon the branch is on (start numbering from the closest single end)Nomenclature for saturated hydrocarbonsa.Alkanes（CnH2n+2烷烃）---+ anefor n<=4：methane (甲烷), ethane(乙烷),propane (丙烷), butane (丁烷).Alkanefor n>4 , for normal alkanesA Greek prefix + ane suffix (if “-aa-”, drop one “a”)5 pent(a)-,6 hex(a)-,7 hept(a)-,8 oct(a)-,9 non(a)-,10 dec(a)-, 11 undec(a)-, 12 dodec(a)-, 13 tridec(a)-,14 tetradec(a)-, 15 pentadec(a)- 16 hexadec(a)-,17 heptadec(a), 18 octadec(a)-, 19 nonadec(a)-,20 eicos(a)-, 22 docos(a)-, 24 tetracos(a)-, 30triacot(a)-, 36 hexatriacot(a)-Eg：nonadecane; C19H40 decanedithiol; HS-C10H22-SH Alkanesn >4 , alkanes’main chain with branchesThe position and name of branch groups are added as prefixes to the name of the longest hydrocarbon chain.
