Question

balance the following chemical equation (if necessary):
pbco₃(s) → pbo(s) + co₂(g)

Explanation:

Step1: Count atoms on both sides

On left side: 1 Pb, 1 C, 3 O. On right side: 1 Pb, 1 C, 3 O.

Step2: Check if balanced

Since the number of each type of atom (Pb, C, O) is the same on both sides of the equation \(PbCO_{3}(s)
ightarrow PbO(s)+CO_{2}(g)\).

Answer:

The chemical equation \(PbCO_{3}(s)
ightarrow PbO(s)+CO_{2}(g)\) is already balanced.
