Question 29 (3 points)

Hydrocarbons are compounds that are made up of only carbon and hydrogen atoms.
Write the skeleton equation and balanced chemical equations, including all states of
matter, for the complete combustion of propane (C3H8). [3 marks]

Answer 1

Step-by-step explanation:

The skeleton equation for the complete combustion of propane (C3H8) is:

C3H8 + O2 -> CO2 + H2O

The balanced chemical equation for the complete combustion of propane (C3H8), including all states of matter, is:

2 C3H8 (g) + 9 O2 (g) -> 6 CO2 (g) + 8 H2O (g)

In this equation, the propane (C3H8) is in the gaseous state, and the oxygen (O2) and the products (CO2 and H2O) are also in the gaseous state. This equation shows that when propane (C3H8) undergoes complete combustion, it reacts with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O) as products. The coefficients in front of each chemical species indicate the number of moles of each substance that are involved in the reaction.
