Answer 1

2Ca + O2 =2CaO
2Na+ S=...Na2S
2K+ Cl2=...2KCl
CuSO4+...NaOH=...NaNo2+SO4+...Cu(OH)2
Zn+ 2HCl =...ZnCl2+ 2HCl
CuCO3=CuO+ CO2
FeCl3+3NaOH = Fe(OH)3+ 3NaCl
NaNO3 = NaNO2 + O2 
(NH4)2CO3= NH3+ CO2+ H2O
NaCl+ AgNo3= AgCl+ NaNO3
Na2SO4+ BaCl2= BaSo4+ 2NaCl
H2CO3 = CO2+ H2O
CaO+ H2O= Ca(OH)2
2Li+ S= Li2S
NaOH+ HCl= NaCl+ H2O
2NaOH+ H2SO4= Na2SO4+ H2O
2H2+ O2= 2H2O
Li+ H = LiH
