написать 10 уравнений вероятных реакций : HCl,P2O5,H2O,NaOH,K20,CO2,Ca

PO + 3HO = 2HPO
6NaOH + PO = 2NaPO + 3HO
Ca + 2HCl = CaCl + H
Ca + 2HO = Ca(OH) + H
3KO + PO = 2KPO
NaOH + HCl = NaCl + HO
KO + 2HCl = 2KCl + HO
2NaOH + CO = NaCO + HO
KO + HO = 2KOH
HO + CO = HCO
KO + CO = KCO

NaOH + HCl = NaCl + H2O
K2O + 2HCl = 2KCl + H2O
Ca + 2HCl = CaCl2 + H2
P2O5 + 3H2O = 2H3PO4
P2O5 + 6NaOH = 2Na3PO4 + 3H2O
3K2O + P2O5 = 2K3PO4
K2O + H2O = 2KOH
H2O + CO2 = H2CO3
Ca + 2H2O = Ca(OH)2 + H2
2NaOH + CO2 = Na2CO3 + H2O
В принципе, можно еще десяток написать.
