Question

P2O5+H2O =, Cao +H2O=, H2O2~MnO2=, SO3+H2O, ​

Answer 1

Ответ:

P2O5 + 3H2O = 2H3PO4

CaO + H2O = Ca(OH)2

H2O2 + MnO2 = MnO + O2 + H2O

SO3 + H2O = H2SO4

Answer 2

These are chemical reactions you've mentioned. I'll provide the balanced chemical equations for each of them:

1. P2O5 + H2O → 2 H3PO4 (Phosphorus pentoxide reacts with water to form phosphoric acid)

2. CaO + H2O → Ca(OH)2 (Calcium oxide reacts with water to form calcium hydroxide)

3. 2 H2O2 + MnO2 → 2 H2O + MnO2 (Hydrogen peroxide decomposes to water and oxygen in the presence of manganese dioxide)

4. SO3 + H2O → H2SO4 (Sulfur trioxide reacts with water to form sulfuric acid)
