Question

Write chemical equations of the following and balance them:(a) Carbon + oxygen ⎯⎯→ Carbon dioxide(b) Hydrogen + Chlorine ⎯⎯→ Hydrogen chloride(c) Barium + Sodium ⎯⎯→ Barium + sodium chloride sulphate sulphate chloride

Answer 1

Balanced equation of the 3 reactions

Explanation:

(a)

2C(s) + O2(g) → 2CO(g)

Carbon, as graphite, burns to form gaseous carbon monoxide.

(b)

H2 + Cl2 → 2HCl

Hydrogen reacts with chlorine to produce hydrogen chloride.

(c)

BaCl₂ + Na₂SO₄ → BaSO₄↓ + 2NaCl.

Barium chloride reacts with liquid sodium sulphate to leave barium sulphate as a precipitate and also forms liquid sodium chloride.
