Question

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

Answer 1

Ответ:

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
