Question

What is the balance of this chemical equation Ca+N2→Ca3N2?

Answer 1

Answer:

The balance of chemical equation is given below.

3Ca + N2------ Ca3N2

Answer 2

Answer:

The balanced chemical reaction is shown below

$3\textrm{Ca}\left ( s \right ) + \textrm{N}_{2}\left ( g \right )\rightarrow Ca_{3}N_{2}\left ( s \right )$

Explanation:

A reaction is said to be a balanced reaction if the number of atoms on both sides of the reaction is equal. The number of atoms of each element has to be made equal in order to balance a chemical reaction.

The unbalanced reaction is shown below

$\textrm{Ca}\left ( s \right ) + \textrm{N}_{2}\left ( g \right )\rightarrow Ca_{3}N_{2}\left ( s \right )$

The number of calcium atoms is not equal on both sides. Hence, we need to multiply Ca by 3 on the left-hand side of the reaction.

The balanced chemical reaction is shown below

$3\textrm{Ca}\left ( s \right ) + \textrm{N}_{2}\left ( g \right )\rightarrow Ca_{3}N_{2}\left ( s \right )$
