Question

Q Ques1. Translate the following statements into balanced chemical equations

a. Hydrogen gas combines with nitrogen to form ammonia.

b. Hydrogen sulphide gas burns in air to give water and sulphur dioxide

c. Barium chloride reacts with ammonium sulphate to ammonium chloride and

precipitate(ppt) of barium sulphate

d. Potasium metals reacts with water to potassium hydroxide and hydrogen gas.

e. Iron fillings react with steam to produce iron (III) oxide and hydrogen gas.

f. Aluminum metal reacts with iron (II) oxide powder to produce aluminum oxide solid

and iron metal.

g. Ammonia gas (NH3) plus oxygen gas yields nitrogen monoxide gas plus water vapour

Calcium hydroxide solution and carbon dioxide gas yields solid calcium carbonate and

liquid water.

h.Aqueous iron (III) chloride and sodium carbonate solution yields aqueous sodium

chloride and a precipitate of iron (III) carbonate.

i.Solid iron (III) oxide and carbon monoxide gas yields iron metal and carbon dioxide

gas.

j.Magnesium carbonate solution plus aqueous hydrochloric acid (HCl) yields magnesium chloride solution plus liquid water and carbon dioxide gas

h.Silicon dioxide solid plus aqueous hydrofluoric acid (HF) yields solid silicon

tetrafluoride plus liquid water

Answer 1

1. N₂ (g) + 3 H₂ (g) →2 NH₃ (g)
2. 2 H₂S (g)+ 3 O₂ (g) → 2 H₂O (g) + 2 SO₂ (g)
3. (NH₄)₂SO₄(aq) + BaCl₂(aq) → BaSO₄(s) + 2 NH₄Cl(aq)
4. 2 K(s) + 2 H₂O(l) → 2 KOH(aq) + H₂(g)
5. 2 Fe(s) + 3 H₂O (g) → Fe₂O₃ (s) + 3 H₂(g)
6. 2 Al (s)+ 3 FeO (s)→ Al₂O₃ (s)+ 3 Fe(s)
7. 4 NH₃ (g) + 5 O₂ (g)→ 6 H₂O (g) + 4 NO(g)
8. 2 FeCl₃(aq) + 3 Na₂CO₃(aq) →6 NaCl(aq) + Fe₂(CO₃)₃(s)
9. Fe₂O₃(s) + 3 CO(g) → 2 Fe(s) + 3 CO₂(g)
10. MgCO₃(aq) + 2 HCl(aq) → MgCl₂(aq) + H₂O(l) + CO₂(g)
11. SiO₂(s) + 4 HF(aq) →SiF₄(s) + 2 H₂O(l)
