H2S+Br2=S+2HBr;2H2SO4+Cu=CuSO4+SO2+2H2O;Na2S+2HCl=2NaCl+H2S;Fe+S=FeS
S+O2=SO2;2SO2+O2=2SO3;SO3+H2O=H2SO4;4FeS2+11O2=2Fe2O3+8SO2.
N:
NH4Cl+NaOH=NH3+NaCl+H2O;4NH3+5O2=4NO+6H2O;2NO+O2=2NO2;3NO2+H2O=2HNO3+NO;
2NO2=N2O4(可逆反应);N2+6H2=2NH3.
H2+S=H2S;H2+FeS2=FeS+H2S;Na2O2+H2SO4=Na2SO4+H2O2;
N:2Na+2NH3=2NaNH2+H2;Na2SO4+4C=Na2S+4CO2;2NaCl+2H2O=2NaOH+Cl2+H2
10K+2KNO3=6K2O+H2;NaNO2+NH4Cl=NaCl+N2+H2O2NH3+Cl2=NH2Cl+NH4Cl
NO+NO2+NaOH=2NaNO2+H2O;N2O3+2NaOH=2NaNO2+H2O;3Na2S+As2O3=2Na3AsS3楼下的,他给那么多分,难打也要打 啊
