Ответ:
а) Ca → CaO:
Ca + O2 → CaO
CaO → Ca(OH)₂:
CaO + H2O → Ca(OH)₂
Ca(OH)₂ → CaCO3:
Ca(OH)₂ + CO2 → CaCO3
б) Mg → MgO:
2Mg + O2 → 2MgO
MgO → Mg(NO3)2:
MgO + 2HNO3 → Mg(NO3)2 + H2O
в) Al(OH)3 → Al2O3:
2Al(OH)3 → Al2O3 + 3H2O
Al2O3 → Al2(SO4)3:
Al2O3 + 3H2SO4 → Al2(SO4)3 + 3H2O
г) CaCO3 → CaO:
CaCO3 → CaO + CO2
CaO → CaCl2:
CaO + 2HCl → CaCl2 + H2O
