2 moles KCl + 3 moles O2 → 2moles KCIO3 Calculate the number of particles of each substance based on the number of moles from the balanced equation

KCl ⇒ 1.205x10²⁴ molecules

O₂ ⇒ 1.807x10²⁴ molecules

KClO₃ ⇒ 1.205x10²⁴ molecules

Explanation:

In order to calculate the number of particles from the number of moles, we have to use Avogadro's number, which states the number of particles in one mol:

So now we multiply the number of moles of each substance by Avogadro's number:

- decrease the number of plants and animals living in the water.
