Answer 2

Let's go through the chemical reactions one by one:

1. Na2O + H2O → 2NaOH Sodium oxide reacts with water to form sodium hydroxide.

2. MgO + H2O → Mg(OH)2 Magnesium oxide reacts with water to form magnesium hydroxide.

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

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

5. SiO2 + H2O → Si(OH)4 Silicon dioxide (silica) reacts with water to form silicic acid.

6. N2O3 + H2O → 2HNO2 Dinitrogen trioxide reacts with water to form nitrous acid.

7. Ni + H2SO4 → NiSO4 + H2 Nickel reacts with sulfuric acid to form nickel sulfate and hydrogen gas.

8. Ag + HCl → AgCl + H2 Silver reacts with hydrochloric acid to form silver chloride and hydrogen gas.

9. Fe(OH)3 → FeO(OH) + H2O Iron(III) hydroxide decomposes to form iron(III) oxide-hydroxide and water.

10. Zn + Hg(NO3)2 → Zn(NO3)2 + Hg Zinc reacts with mercury(II) nitrate to form zinc nitrate and mercury.

11. Mg + CuCl2 → MgCl2 + Cu Magnesium reacts with copper(II) chloride to form magnesium chloride and copper.

12. C + H2 → CH4 Carbon reacts with hydrogen gas to form methane.
