Chemistry
Explain the term 'chemical equation'. What is meant by 'reactants' and 'products' in a chemical equation.
Answer
Chemical equation is a shorthand form for a chemical change. It shows the result of a chemical change in which the reactants and the products are represented by:
- symbols [in the case of elements]
- formula [in the case of compounds]
The substances which take part in a chemical change and are written on the left side of the equation are called the reactants.
The substances formed as a result of a chemical change and are written on the right side of the equation are called the products.
E.g., NH3 + H2O ⟶ NH4OH
Here, NH3 and H2O are reactants and NH4OH is the product.
