Complete the reaction equations, write the molecular and ionic reaction equations where possible: 1) CaO + CO2 = 2) CaO + HCl = 3) CaO + SiO2 = 4) CaCO3 + HNO3 = 5) CaCO3 + HCl = 6) CaCO3 + SiO2 =

1) CaO + CO2 = CaCO3↓;

2) CaO + 2HCl = CaCl+ H2O;

CaO + 2H+ 2Cl– = Ca2+ + 2Cl– + H2O;

CaO + 2H= Ca2+ + H2O;

3) CaO + SiO2 = CaSiO3;

4) CaCO3 + 2HNO3 = Ca(NO3)+ H2O + CO2↑;

Ca2+ + CO32- + 2H+ 2NO3– = Ca2+ + 2NO3– + H2O + CO2↑;

CO32- + 2H= H2O + CO2↑;

5) CaCO3 + 2HCl = CaCl+ H2O + CO2↑;

Ca2+ + CO32- + 2H+ 2Cl– = Ca2+ + 2Cl– + H2O + CO2↑;

6) CaCO3 + SiO2 = CaSiO3 + CO2↑;

Ca2+ + CO32- + SiO2 = Ca2+ + SiO32- + CO2↑;

CO32- + SiO2 = SiO32- + CO2↑;
