Solution
- Reactants
Left hand side write the reactants (substances which take part in a reaction).
- Products
Right hand side write the products (substances formed as a result of the reaction).
Chemical equation formed is
\[\ce{\underset{\text{[dil.]}}{Zn} + H2SO4 -> ZnSO4 + H2[g]}\]
The function of the arrow (→) between the reactants and products is that it represents the chemical reaction taken place between two reactants.
