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
