Answer 1

Al.

Answer 2

Could you please explain how you got Al as the limiting reactant? if it's not any trouble.

Answer 3

I aprreciate the response, but an explanation along with it would suffice.

Sorry! i had gone out, uhm, let me see here.

Answer 6

Well, when you look 4.5 moles of aluminum react with 6.7 moles of oxygen gas and the equation Al + O2-->AL2O3 it is 1 mole of Al reacts with 1 mole of O2 because there is nothing before the Al or O2, meaning the ratio is 1:1 Therefore you will run out of Al before you do O2. But! If it were like this (Al + 3O2-->AL2O3) the ratio would be 3:3. In which you would run out of O2 before Al.
