What is the word equation for KNO3 = KNO2 + O2

Potassium nitrate potassium nitrite + oxygen

Explanation:

Word equation:

Potassium nitrate potassium nitrite + oxygen

Chemical equation:

KNO₃ → KNO₂ + O₂

Balanced chemical equation:

2KNO₃ → 2KNO₂ + O₂

Now the given equation is balanced because there are equal number of atoms of potassium, nitrogen and oxygen are present on both side of equation.

This reaction completely follow the 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.

Reaction type:

The given reaction is decomposition reaction.

Decomposition reaction:

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

AB → A + B
