Answer 1

I've answered this already, yet. Your answer to #1 was/is correct.
Look at the balanced equation (I wrote the balanced equation in my response.) The correct answer STILL is oxygen BECAUSE there is a coefficient of 5 for O2 and 5 is the largest number in the equations set of coefficients.

Answer 2

The answer is oxygen
