Nitrogen monoxide and oxygen, both colorless gases, form a red-brown gas when mixed. nitrogen monoxide and oxygen are called the

Nitrogen monoxide and oxygen are called the reactants

Explanation:

Step 1: Given data

Nitrogen monoxide = NO

Oxygen = O2

Step 2: Balanced equation

2NO + O2 → 2NO2

This means that 2 moles of NO will be consumed and and 1 mole of O2 to produce 2 moles of NO2

This means NO2 is the prodcut that is produced.

NO +O2 react with eachother, to form NO2

This means nitrogen monoxide (NO) and Oxygen (O2) are called the reactants.

the temperature of the gas, in k, not celsius.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
