To balance this equation, we have to write out the chemical formula of lead(iv)oxide.

The chemical formula of lead(iv)oxide is

[tex]\text{PbO}_2[/tex]

The decomposition of lead(iv) oxide will occur when heated at a high temperature to produce lead(ii) oxide.

[tex]PbO_2\rightarrow PbO+O_{}_{}[/tex]

Let us balance the reaction above.

Applying the law of conservation of matter i.e

Since we have 1 atom of Pb in the reactant side and 1 atom of Pb in the product side, that should be balanced.

But the oxygen isn't yet balanced.

Add 2 in front of both sides i.e PbO₂ and PbO to make the equation balanced.

The equation would become

[tex]2\text{PbO}_2\rightarrow2PbO+O_2[/tex]

If we look at the Pb

reactant = 2

product = 2

for the oxygen side

reactant = 4

product = 4

The balanced equation to represent the decomposition of lead(iv)oxide is given as

[tex]2\text{PbO}_2\rightarrow2PbO+O_2[/tex]
