Chapter 22, Problem 22.48QP

Interpretation Introduction

Interpretation: The balanced chemical equation for the thermal decomposition of aluminium nitrate has to be written.

Concept Introduction:

Thermal decomposition:

It is also known as thermolysis. It is the process in which a chemical decomposition takes place by the supply of heat energy. The word “thermos” means heat and “lysis” is the suffix word which represents the cleavage or decomposition process.

Balanced equation:

• It is a chemical equation in which the number of each type of atoms will be equal in the stoichiometric ratios on both the sides of the equation.
• The concept of writing a balanced chemical equation is based on the law of conversion of mass
• According to the law of conversion of mass, in a chemical reaction the mass of total amount of the product should be equal to the total mass of the reactants.
• First write the reaction from the given information.
• Then count the number of atoms of each element in reactants as well as products.
• Insert some positive integers as coefficients of reactants as well as products in order to get the equal number of all elements on both sides of the equation.
