How many miles of CO2 are produced if 1.50 miles of C3H8 combust

Answer 1

In a combustion reaction, the hydrocarbon (C3H8) will always react with oxygen gas, or O2. The end products formed in a combustion reaction are always carbon dioxide (CO2) and water H2O.

To do this question, you must write the chemical reaction and balance it. Balancing the equation means making sure there are the same amount of each atom in the left and right side of the equation.

In this case:

C3H8 + 5O2 = 3CO2 + 4H2O

We start off with 1.5 moles and the coefficient for each molecule tells us how many moles of each are there. Then, do a conversion from moles of C3H8 to moles of CO2.

Therefore, 1.5 mol of C3H8 (3 mol of CO2/ 1 mol of C3H8) = 4.5 moles of CO2 (answer).
