Answer 3

hopefully this helps

Answer 4

sorry I cant figure it out

Answer 5

is it 4?

Answer 6

I think so, either 4 or 3 but i am pretty sure it is 4

Answer 8

First balance the reaction

\(\text{ __C}_2\text{H}_5\text{OH} + \text{__O}_2 \to \text{__CO}_2 + \text{__H}_2\text{O}\)

If we have \(1~\text{C}_2\text{H}_5\text{OH}\) then we have 2 Carbons, 6 Hydrogens (5 + 1) and 1 oxygen

First try to balance the right side. We have 2 carbons on the left side. What will the coefficient of CO2 be then so that you have 2 carbons on both sides of the equation?

We also have 6 hydrogens in the C2H5OH molecule. How many H2O would we need for there to be 6 hydrogens on both sides?
Keep in mind that H2O has 2 hydrogens so 2 times what gives you 6? That's going to be the coefficient for H2O


Once you find that, we can then find the coefficient for O2
