Закончите уравнения реакций:
1.LI + O=
2.H2 + 02=
3.Cr2O3 + H2=
4.Mg + HCl=
5 H2 +N2=
6.C H4 + O2=
7.Ca + O2=
8.P + O2=
9.CuO + H2=
10.Zn + HCI=
11.H2 + O2=
12.H2S + O2=

Answer 1

4Li+O2=2Li2O
2H2+O2=2H2O
Cr2O3+3H2=2Cr+3H2O
Mg+2HCl=MgCl2+H2
3H2+N2=2NH3
CH4+2O2=CO2+2H2O
2Ca+O2=2CaO
4P+5O2=2P2O5
CuO+H2=Cu+H2O
Zn+2HCl=ZnCl2+H2
2H2+O2=2H2O
2H2S+3O2=2SO2+2H2O
