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.

Answer 1

Answer:

Propane gas plus oxygen gas produces water and carbon dioxide.

Explanation:

This is the initial chemical equation: C3H8 + O2 = CO2 + H2O

This is the balanced chemical equation: C3H8 + 5 O2 = 3 CO2 + 4 H2O

Answer 2

1. Propane gas plus oxygen gas produces carbon dioxide and water.
2. The balanced chemical equation is as follows: C3H8 + 5O2 → 3CO2 + 4H2O

• Propane 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
