how many grams of oxygen are produced if 25.0g of potassium chlorate decomposes according to the reaction 2KCLO3 —-> 2KCL +3O2

9.79g of O2

Explanation:

So this question you are trying to go from g of KCLO3 to grams of oxygen. There is no direct conversion so you have to utilize multiple process.

=9.79 g of O2

So first you go from g of KCLO3 to moles of KCLO3  by using molar mass of KCLO3. Then you use mol:mol ratio from balanced equation to go to moles of O2, and finally use molar mass of O2 to go to grams of O2.

the answer is alpha particles hope i you

personal, she chose to do it.
