Answer:
The balanced hemical equation is given below. 18 moles of oxygen are produced.
When 2 moles of Potassium chlorate decomposes to produce 2 moles of potassium chloride and 3 moles of oxygen gas. The balanced chemical equation for this decomposition reaction follows:
By Stoichiometry of the reaction,
2 moles of potassium chlorate produces 3 moles of oxygen gas
So, 12 moles of potassium chlorate will produce = of oxygen gas.
Hence, 18 moles of oxygen gas will be produced.
