Question

When heated, KClO3KClO3 decomposes into KClKCl and O2.O2.

 

2KClO3⟶2KCl+3O22KClO3⟶2KCl+3O2

 

If this reaction produced 39.6 g KCl,39.6 g KCl, how many grams of O2O2 were produced?

mass:        g O2
Expert Solution
Step 1

The balanced equation is

2KClO3⟶2KCl+3O2

When 2 mole of KClO3 decomposes , 2 moles of KCl and 3 moles of O2 are produced

By comparing the number of moles of KCl and O2, we find the number of moles of O2 and then mass of O2.
