Read the word equation: “Propane gas plus oxygen gas produces .” b) Convert the word equation to a chemical equation and complete the reaction. Be sure to balance
the chemical equation.
c) Record the balanced chemical equation on the Student Worksheet.

Propane gas plus oxygen gas produces carbon dioxide and water. The balanced chemical equation is as follows: C3H8 + 5O2 → 3CO2 + 4H2OPropane is a member of the alkane group with the chemical formula; C3H8 while oxygen gas has the chemical formula; O2. Propane gas (C3H8) and oxygen gas (O2) combines to produce carbon dioxide (CO2) and water (H2O). The chemical equation is as follows:

C3H8 + O2 → CO2 + H2O

However, the above equation is not balanced. To balance it, we make use of coefficients to make the number of atoms of each element equal. The balanced equation is as follows:

C3H8 + 5O2 → 3CO2 + 4H2O
