Predict the products of the decomposition of lithium nitride, Li3N.

Lithium nitride decompose to give lithium and nitrogen

Explanation:

Chemical equation:

Li₃N → Li + N₂

Balanced chemical equation:

2Li₃N → 6Li + N₂

The given reaction is a decomposition reaction.

Decomposition reaction:

It is the reaction in which one reactant is break down into two or more product.

AB → A + B

In given reaction lithium nitride decompose and give lithium and nitrogen.

This reaction also follow the law of conservation of mass because there are equal number of atoms of each element present on both side.

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
