Question

Give an example of each of the following chemical changes:
(b) An exothermic and endothermic reaction involving carbon as one of the reactants.

Open in App

Solution

Exothermic reaction involving carbon as one of the reactants: When carbon burns in oxygen to form carbon dioxide, a lot of heat is produced. That is,
$C + O_{2} \to {C O}_{2} +$ Heat
Endothermic reaction involving carbon as one of the reactants:
When carbon is heated with sulphur at high temperature, liquid carbon disulphide is formed. That is,
$C + 2 S Δ \to {C S}_{2}$
