1) 2Са + О2 = 2СаО – the reaction of the compound.
CaO + H2O = Ca (OH) 2 – compound reaction.
Ca (OH) 2 + HNO3 = Ca (NO3) 2 + H2O – exchange reaction.
Ca (NO3) 2 + H2SO4 = CaSO4 + 2HNO3 – exchange reaction.
2) С + О2 = СО2 – compound reaction.
СО2 + Na2О = Na2CO3 – compound reaction.
Na2CO3 + 2HCl = 2NaCl + (H2CO3) + CO2 + H2O – when hydrochloric acid is added to the sodium salt, carbonic acid is formed, which is not stable and immediately decomposes into carbon dioxide and water.
CO2 + CaO = CaCO3 – compound reaction.
