Написать 10 уравнений возможных реакций : hcl,p2o5,h2o,naoh,k20,co2,ca

P₂O₅ + 3H₂O = 2H₃PO₄
6NaOH + P₂O₅ = 2Na₃PO₄ + 3H₂O
Ca + 2HCl = CaCl₂ + H₂
Ca + 2H₂O = Ca(OH)₂ + H₂
3K₂O + P₂O₅ = 2K₃PO₄
NaOH + HCl = NaCl + H₂O
K₂O + 2HCl = 2KCl + H₂O
2NaOH + CO₂ = Na₂CO₃ + H₂O
K₂O + H₂O = 2KOH
H₂O + CO₂ = H₂CO₃
K₂O + CO₂ = K₂CO₃

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.
