Answer 2

Chemical Reactions:

Here is a detailed explanation of the chemical reactions for the given compounds:

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

2. Na2O + H2O → 2NaOH - Sodium oxide (Na2O) reacts with water (H2O) to produce sodium hydroxide (NaOH) [[2]].

3. K2O + H2O → 2KOH - Potassium oxide (K2O) reacts with water (H2O) to form potassium hydroxide (KOH) [[3]].

4. KCl + H2O → KCl + H2O - Potassium chloride (KCl) dissolves in water (H2O) to form a solution of potassium chloride [[4]].

5. P2O5 + H2O → H3PO4 - Phosphorus pentoxide (P2O5) reacts with water (H2O) to produce phosphoric acid (H3PO4) [[1]].

6. SO3 + H2O → H2SO4 - Sulfur trioxide (SO3) reacts with water (H2O) to form sulfuric acid (H2SO4) [[5]].

7. Na2SO4 + H2O → Na2SO4 + H2O - Sodium sulfate (Na2SO4) dissolves in water (H2O) to form a solution of sodium sulfate [[6]].

8. CaO + H2O → Ca(OH)2 - Calcium oxide (CaO) reacts with water (H2O) to produce calcium hydroxide (Ca(OH)2) [[7]].

9. CaO + SiO2 → CaSiO3 - Calcium oxide (CaO) reacts with silicon dioxide (SiO2) to form calcium silicate (CaSiO3) [[8]].
