Answers

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
