Expert Answer:

Zn + 2HCl    = ZnCl2+H2
 
Na2CO3 +2HCl = 2NaCl+ CO2+H2O
 
 
NaHCO3+HCl = NaCl +CO2+H2O
 
 
NaOH +HCl = NaCl + H2O
 
CuO+ 2HCl= CuCl2+ H2O
 
CaCO3+ H2SO4 =CaSO4 +CO2+ H2O
 
HCl + H2O = H3O++ Cl-
 
 
Ca(OH)2 +CO2 = CaCO3 + H2O
 
 
2NaOH+ H2SO4 = Na2SO4+2 H2O
 
CaCO3 + CO2+ H2O = Ca(OH)2+H2CO3
