Chapter 1, Problem 20Q

These questions relate to the combustion of hydrocarbons.

1. a. LPG (liquid petroleum gas) is mostly propane, C₃H₈. Balance this equation.

${\text{C}}_3{\text{H}}_8(g)+{\text{O}}_2(g)\to {\text{CO}}_2(g)+{\text{H}}_2\text{O}(g)$

1. b. Cigarette lighters burn butane, C₄H₁₀. Write a balanced equation for the combustion of butane.
2. c. With a limited supply of oxygen, both propane and butane can burn incompletely to form carbon monoxide. Write balanced equations for both reactions.
