PLEASE HELP

In the equation 2KCIO3 → 2KC1 + 302, how many moles of oxygen are produced when 3.0 mol of KCIO3 decompose completely? ​

Answer 1

Moles of Oxygen produced : 4.5 moles

Further explanation

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

The reaction coefficient shows the mole ratio of the reactants and products

Reaction

2KCIO₃ → 2KCl + 30₂

moles of KCIO₃ = 3

From equation, mol ratio of KCIO₃ : O₂ = 2 : 3, so mol O₂ :

`\tt mol~O_2=(3)/(2)* 3=4.5`
