i already told him dont tell him again

Answer 13

What did you get?

Answer 14

2C3H7OH+9O2 --> 6CO2+8H2 its difficult to balance this.

Answer 15

8H2O

Answer 16

Correct. You have 2 moles of propyl alcohol and are burning it by reacting it with 9 moles of oxygen gas.

Answer 17

I don't understand.

Answer 18

2C3H7OH + 9O2 is what you're starting with.

Answer 19

okay then I convert to moles?

Answer 20

For every 2 C3H7OH you have you need 9 O2.
You can pick any number of molecules, like say, a dozen.
For every 2 dozen propyl alcohol you need 9 dozen oxygen.

Answer 21

oh okay, thanks.

Answer 22

You can use the word dozen or mole interchangeably.
Just remember, dozen means 12.
Mole means 602214129270000000000000.

Answer 23

got you, thank you.
