Answer 1

2PH₃ + 4O₂ = P₂O₅ + 3H₂O

Ca(OH)₂  =  CaO + H₂O

Pb(OH)₂ = PbO + H₂O

BaCO₃   = BaO + CO₂↑

FeCO₃   = FeO + CO₂↑

K₂SiO₃   = SiO₂ + K₂O

MgO + CO₂ = MgCO₃↓

BaO + SO₂ = BaSO₃

Li₂O + SO₃ = Li₂SO₄

PbO + 2HNO₃ = Pb(NO₃)₂ + H₂O

MgO + H₂SO₄ = MgSO₄ + H₂O

ZnO + 2HNO₃ = Zn(NO₃)₂ + H₂O

K₂O + H₂S = K₂S + H₂O

FeO + 2HNO₃ = Fe(NO₃)₂ + H₂O 

BaO + H₂CO₃ = BaCO₃↓ + H₂O

Na₂O + 2HBr = 2NaBr + H₂O

CaO + H₂CO₃ = CaCO₃↓ + H₂O

PbO + 2HCl = PbCl₂ + H₂O

CaO + H₂O = Ca(OH)₂

Li₂O + H₂O = 2LiOH
