Ca + 2H2O = Ca(OH)2 + H2 + 413 кДж
Ca + S = CaS
Ca + H2 (t°) = CaH2
Ca + V2O5 = 2V + 5CaO
Ca + 3Sn (t°) = CaSn3
2Ca + Sn (t°) = Ca2Sn
Ca + 10HNO3 (разб) = 4Ca(NO3)2 + NH4NO3 + 3H2O
4Ca + 10HNO3 (конц) = 4Ca(NO3)2 + N2O + 5H2O
4Ca + 5H2SO4 (конц) = 4CaSO4 + H2S + 4H2O
CaO + H2O = Ca(OH)2 + 64 кДж
3CaO + 2Al = 3Ca + Al2O3
Ca(OH)2 (t°) = CaO (негашеная известь) + H2O↑
Ca3P2 + 6HCl = 3CaCl2 + 2PH3
