(реакция разложения)

Answer 2

Balancing the Chemical Equation and Identifying Reaction Types

To balance the chemical equation for the reaction involving KNO3, KNO2, and O2, we can use the following equation:

KNO3 → KNO2 + O2

First, let's balance the equation by adding coefficients to the reactants and products. Then, we'll identify the type of reaction.

The balanced equation is:

2KNO3 → 2KNO2 + O2

This balanced equation indicates that 2 moles of potassium nitrate (KNO3) react to produce 2 moles of potassium nitrite (KNO2) and 1 mole of oxygen (O2).

Type of Reaction

The type of reaction can be identified as a decomposition reaction. This is because a single compound (KNO3) breaks down into two or more simpler substances (KNO2 and O2).
