How many grams of O2 are formed from 13.34 moles of KClO3? Provide your final answer rounded to two decimal places. 2 KClO3 → 2 KCl + 3 O2

640.32 g

Explanation:

2KClO₃ → 2KCl + 3O₂

First we convert KClO₃ moles to O₂ moles, using the stoichiometric coefficients:

Then we convert O₂ moles to grams, using its molar mass:

So 640.32 g of O₂ are formed from 13.34 moles of KClO₃.

the answer is d. 74.02

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
