Question

Write the formulae of the following chemical compounds:
Ammonia

Answer 1

To write the formulae of any chemical compound we follow the given steps:

1. Write the symbols for the elements present in the compound.
2. Write their respective valencies below the symbols.
3. Using the criss-cross arrows, assign the second valency to the forts element and the first valency to the second element.
4. For complete formula, write the numerals in the subscript of the symbols of elements.

The formula of Ammonia will be :

Name of elements: Nitrogen Hydrogen

Symbols of elements: N H

Valency of elements: 3 1

Formula: ${\mathrm{NH}}_3$

Hence, the formula of Ammonia is ${\mathrm{NH}}_3$.
