Please help me answer Question 1.

9 moles of oxygen are produced from 6 moles of potassium chlorate.

Explanation:

Given data:

Number of moles of KClO₃ = 6 mol

Number of moles of oxygen produced = ?

Solution:

Chemical equation:

2KClO₃       →    2KCl  + 3O₂

now we will compare the moles of KClO₃ and O₂.

                     KClO₃          :        O₂

                         2              :         3

                         6              :        3/2×6 = 9

Thus, 9 moles of oxygen are produced from 6 moles of potassium chlorate.
