Answer:
Explanation:
Let's just get the answer and then show why the others are wrong.
The answer is C.
The number of reactants and Products need not be the same
C3H8 + 5O2 ===> 3CO2 + 4H2O
The reactants = 1 + 5 = 6
The products = 3 + 4 = 7
So A is incorrect.
================
B is saying that
C3H8 + 5O2 ===> C3H8 + 5O2
The answer is obviously not B
======================
C8H18(l) + O2(g) ==> CO2(g) + H2O(g) unbalanced
Gasoline is a liquid. All the rest are gases. D is wrong.
=================
C is correct
The left side has
3 Cs
8 Hs
and 10 Os
The right side has
3Cs
8Hs
10 Os

B- the temperature is the information you should look for

Explanation:
I did a few quick Google searches on ap classes because I myself do not take them a I read that most colleges do take ap classes as credit. it's no guaranteed however as it says many, not all. and for C I looked it up and I'm assuming they can be taken anywhere. take what I say with a grain of salt though because like I said I just googled it, hope it helps though.
