Answer 2

Equations of Reactions:

1. H3PO4 + Na2O = HCl + Na + H2SO4 + NaOH + HNO3 - Phosphoric acid (H3PO4) reacts with sodium oxide (Na2O) to produce hydrochloric acid (HCl), sodium (Na), sulfuric acid (H2SO4), sodium hydroxide (NaOH), and nitric acid (HNO3).

2. CuS + HNO3 = Cu(NO3)2 + NO + S + H2O - Copper(II) sulfide (CuS) reacts with nitric acid (HNO3) to produce copper(II) nitrate (Cu(NO3)2), nitrogen monoxide (NO), sulfur (S), and water (H2O).

3. MgO + H2SO3 = MgSO3 + H2O - Magnesium oxide (MgO) reacts with sulfurous acid (H2SO3) to produce magnesium sulfite (MgSO3) and water (H2O).

4. K2O + HBr = KBr + H2O - Potassium oxide (K2O) reacts with hydrobromic acid (HBr) to produce potassium bromide (KBr) and water (H2O).

5. Mg + H2SiO3 = MgSiO3 + H2 - Magnesium (Mg) reacts with silicic acid (H2SiO3) to produce magnesium silicate (MgSiO3) and hydrogen gas (H2).

6. KOH + H2S = KHS + H2O - Potassium hydroxide (KOH) reacts with hydrogen sulfide (H2S) to produce potassium hydrosulfide (KHS) and water (H2O).

7. Pb(NO3)2 + 2HI = PbI2 + 2HNO3 - Lead(II) nitrate (Pb(NO3)2) reacts with hydroiodic acid (HI) to produce lead(II) iodide (PbI2) and nitric acid (HNO3).

8. AgNO3 = AgI + HNO3 - Silver nitrate (AgNO3) decomposes to produce silver iodide (AgI) and nitric acid (HNO3).
