Write equations for the following reactions:

the combustion of propane

the incomplete combustion of propane to for CO and water

the complete combustion of 8,8-dimethylpropane in oxygen

the third question it should be 2 not 8

All of these are the combustion of a hydrocarbon with oxygen. The products, in all cases, are CO2 and water unless other products are given specifically as in #2.

Sure!

1. The combustion of propane (C₃H₈) can be represented by the following equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

In this reaction, propane (C₃H₈) reacts with oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O).

2. The incomplete combustion of propane (C₃H₈) to form carbon monoxide (CO) and water (H₂O) can be represented by the following equation:
2C₃H₈ + 9O₂ → 4CO + 4CO₂ + 8H₂O

In this reaction, propane (C₃H₈) reacts with oxygen (O₂) to produce carbon monoxide (CO), carbon dioxide (CO₂), and water (H₂O).

3. The complete combustion of 8,8-dimethylpropane (C₁₀H₂₂) in oxygen (O₂) can be represented by the following equation:
C₁₀H₂₂ + 15O₂ → 10CO₂ + 11H₂O

In this reaction, 8,8-dimethylpropane (C₁₀H₂₂) reacts with oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O).

Please note that these balanced equations represent the stoichiometric ratios of the reactants and products based on the law of conservation of mass.
