Question 1.

A Compound Containing 3 Atoms Of Carbon & 8 Atoms Of Hydrogen Is Combined In A Reaction With Oxygen Molecules. The 2 End Products Of This Equation Are Carbon Dioxide &water. What Element Should You Look At 1st In Balancing This Equation? Choose a.b.c or d?
A. Oxygen
b. Hydrogen
c. Carbon
d. Dioxide

Question 2 NEW QUESTION
When you have finished balancing the equation for the above question, which chemical element will have the largest number of molecules in your balanced equation? Choose a. B. C. Or d?
A. The C3H
b. The oxygen
c. The carbon dioxide
d. The water

I believe the correct answer is to question 1 - C.

C3H8 + O2 -----> CO2 + H2O

And the answer to question 2 is D.
Option D) The water has the largest number of molecules in the balanced equation.

AM I RIGHT?????

2 answers

I would go with 1C also, carbon.
The balanced equation I have is
C3H8 + 5O2 ==> 3CO2 + 4H2O

Now which has the largest number. Also, note the question is, "Which ELEMENT has..."
1C
