Question

i) Write balanced equations for the following reactions:
(a) Aluminum + Copper chloride → Aluminum chloride + Copper:
(b) Magnesium + Hydrochloric acid → Magnesium chloride + Hydrogen:

Hint:

When balancing chemical equations, ensure that the number of atoms for each element is the same on both sides of the equation. Always start with balancing metals and then non-metals.

Answer 1

(a) Aluminum + Copper chloride → Aluminum chloride + Copper:
The balanced chemical equation for this reaction is: \[ 2Al + 3CuCl_2 \rightarrow 2AlCl_3 + 3Cu \] (b) Magnesium + Hydrochloric acid → Magnesium chloride + Hydrogen:
The balanced chemical equation for this reaction is: \[ Mg + 2HCl \rightarrow MgCl_2 + H_2 \]
