If 0.525 moles of O2 are produced, how many moles of KClO3 are decomposed?

B. 0.35mol KClO3

Explanation:

The balanced equation in this question is given as follows:

2KClO3 → 2KCl + 3O2

Based on the chemical reaction;

2 moles of KClO3 decomposes into 3 moles of O2

If 0.525 moles of O2 are produced, then:

= 0.525 × 2/3

= 1.05/3

= 0.35mol of KClO3 is decomposed.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
