Question

Химия: CaO + HNO₃ = CaO + H₂SO₄ = CaO + H₂CO₃ = Al + HNO₃ = Al + H₃PO₄ = Al + H₂S = Al + H₂SO₃ =

Этоясказал · Answer

CaO + 2HNO3 = Ca(NO3)2 + H2O

CaO + H2SO4 = CaSO4 + H2O

CaO + H₂CO₃ = CaCO3 + H20

2Al + 6HNO₃ = 2Al(NO3)3 + 3H2

2Al + 2H₃PO₄ = 2AlPO4 + 3H2

2Al + 3H₂S = Al2S3 + 3H2

2Al + 3H₂SO₃ = Al2(SO3)3 + 4H2
