20XX年高三化学复习知识系统归纳（ Systematic summary of chemistry review in grade three of senior high school in 2010） Chemistry is easy to forget knowledge One, save with liquid bromine: a thin layer of water then cover and airtight stored in low temperature. hydrobromide: kept in plastic bottles. new green water: sealed with brown reagent bottle. iodine: kept in a brown reagent bottle and placed in the dark. Two, the role of matter chlorine: as disinfectant. : silver bromide film, photographic paper AgI: artificial rainfall iodine: prevention of goiter starch: to test the existence of iodine element sodium hypochlorite: bleaching textiles Three, balance problems are easy to ignore nitrogen dioxide: the balance between the presence and the four nitrogen oxides the equilibrium constant is only related to temperature, and has nothing to do with the concentration and pressure. Four, we should pay attention to the A Vogadero constant rare gases are monatomic molecules gas should be used only in the standard condition three sulfur oxide, the standard condition is solid; benzene, toluene, carbon tetrachloride, hexane standard condition is liquid. hydrolysis of iron ion, aluminum ion, ammonium ion, and ionization of weak electrolyte white phosphorus P4, between phosphorus and phosphorus is the key six someorganic compoundshave the samenumber of chemical bonds in isomers 7) Five, matter and its chemical formula fluorite CaF2 barite -- BaSO4 quartz (optical fiber) SiO2 gypsum -- CaSO4. 2H2O mature gypsum -- 2CaSO4. H2O brochantite (blue vitriol) - CuSO4 5H2O. melanterite - FeSO4. 7H2O alum - KAl (SO4) 2. 12H2O goslarite - ZnSO4 7H2O. awn alum -- NaSO4. 10H2O soda - Na2CO3 bicarbonate of soda - NaHCO3 soda - Na2S2O3. 10H2O Six, metal lightest lithium the heaviest osmium lowest melting point mercury the highest melting point tungsten maximum hardness chromium the content of aluminum is the most in the earth crust the best conductivity is silver ductility is best -- gold Seven, element cycl
