(i) Mg(s) + …….HCl(aq) → …….MgCl2 (aq) + ……H2 (g) (ii) P4O10(s) +……..C(s) → ………P4(s) + …..CO2(g) (iii) AgNO3(aq) + ….NaBr(aq) → …….AgBr(s) + ……NaNO3(aq) (iv) Ba(OH)2(aq) + …H2SO4 (aq) → ……BaSO4(s) + …..H2O(l) (v) Cl2(aq) + …….KBr(aq) → ……..Br2(aq) + …….KCl(aq) (vi) SO3(g) → ……..O2(g) + …….SO2(g)

Answer 1

(I) Mg(s) + 2HCl(aq) →MgCl₂(aq) + H₂(g)

Substitution reaction

Redox

(II) P₄O₁₀(s) + 5C(s) → P₄(s) + 5CO₂(g)

Substitution reaction

Redox

(III) AgNO₃(aq) + NaBr(aq) → AgBr(s) + NaNO₃(aq)

Salt metathesis reaction

(IV) Ba(OH)₂(aq) + H₂SO₄ (aq) →BaSO₄(s) + 2H₂O(l)

Salt metathesis reaction

(V) Cl₂(aq) + 2KBr(aq) → Br₂(aq) + 2KCl(aq)

Substitution reaction

Redox

(VI) 2SO₃(g) → O₂(g) + 2SO₂(g)

Reaction decomposition

Redox
