The equation that is a decomposition reaction is
PbCO3(s) ---> PbO(s) + CO2(g)
That is option D.
<h3>Properties of a decomposition reaction</h3>
A chemical reaction is defined as the combination of substances called reactants to form a product. The various types of chemical reaction include:
- single or double replacement reaction
Decomposition reaction is that type of chemical reaction in which the reactant breaks down to form two or more products.
Therefore the heating of lead (II) carbonate is a decomposition reaction.
