Two moles of potassium chloride and three moles of oxygen are produced from the decomposition of two moles of potassium chlorate, kcos3(s). write the balanced equation. how many moles of oxygen are produced from 12 moles of potassium chlorate

The balanced hemical equation is given below. 18 moles of oxygen are produced.

Explanation:

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.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
