Question

Quizplus · Accepted Answer

The burning of coal primarily produces carbon dioxide, which is a greenhouse gas and contributes to global warming. Sulfur dioxide is also produced, but typically from burning coal that contains sulfur compounds, whereas not all coal contains sulfur. Carbon monoxide is produced from incomplete combustion, which should be avoided for safety and environmental reasons. Oxygen is not a byproduct of the burning of coal.
