Question

помогите с химией пожалуйста

Answer 1

1) СaCl2 = Ca + Cl2

2) Ca + 2H2O = Ca(OH)2 + H2

3) Ca(OH)2 + CO2 = CaCO3 + H2O

4) CaCO3 = CaO + CO2

5)3CaO + P2O5 = Ca3(PO4)2

6) Ca + 2CH3COOH -> (CH3COO)2Ca + H2

(CH3COO)2Ca + H2SO4 = 2CH3COOH + CaSO4

CH3COOH + CH3-CH2-OH -> CH3COOCH2CH3 + H2O
