Question

any units will do. for example, lets use the unit of \dozens\:
2 dozen of h₂ particles + dozen of o₂ particles → dozen water particles

Explanation:

Step1: Write the chemical equation

The chemical equation for the reaction between hydrogen and oxygen to form water is \(2H_{2}+O_{2}
ightarrow 2H_{2}O\).

Step2: Substitute the unit

Since we are using the unit of "dozens", we substitute the coefficients in the chemical equation with the number of dozens. So, \(2\) dozen of \(H_{2}\) particles \(+ 1\) dozen of \(O_{2}\) particles \(
ightarrow 2\) dozen water particles.
