Question

A thermal decomposition reaction of a salt which results in the formation of nitrogen gas

Answer 1

The thermal decomposition reaction of a salt, Lead Nitrate [Pb(NO3)2] results in the formati of nitrogen gas.

Answer 2

The given question is A thermal decomposition reaction of a salt which results in the formation of nitrogen gas.

Here,we have to find the salt.

The answer is Lead Nitrate $[Pb(NO_{3} )_{2} ]$

Thermal decomposition reaction becomes common in everyday life.

sodium hydrogen carbonate, also called baking soda, thermally decomposes when you bake muffins

This is the example of thermal decomposition in everyday life.

The baking soda used in every eatables to get fluffy  foods.

Mercury oxide, copper carbonate, copper sulphate, copper hydroxide, sodium nitrate, lead carbonate, and zinc carbonate are the components  undergoes thermal decomposition.

Therefore ,the answer is Lead Nitrate which undergoes thermal decomposition results in the formation of nitrogen gas.
