составьте уравнение реакций превращений Ca->CaO->Ca(OH)2->Ca(HCO3)2-> CaCO3->Ca(NO3)2 срочно надо
2Ca + O2 = 2CaO CaO + 2HNO3 = Ca(NO3)2 + H2O Ca(NO3)2 + Na2CO3 = CaCO3 + 2NaNO3 CaCO3 + CO2 + H2O = Ca(HCO3)2 Ca(HCO3)2 (t) = CaCO3 + CO2 + H2O CaCO3 (t)= CaO + CO2 CaO + H2O = Ca(OH)2

2Ca + O2 = 2CaO
CaO + 2HNO3 = Ca(NO3)2 + H2O
Ca(NO3)2 + Na2CO3 = CaCO3 + 2NaNO3
CaCO3 + CO2 + H2O = Ca(HCO3)2
Ca(HCO3)2 (t) = CaCO3 + CO2 + H2O
CaCO3 (t)= CaO + CO2
CaO + H2O = Ca(OH)2
