CaRbon dioxide.
The "kind" called Carbon Monoxide. In other words, you don't get Carbon Dioxide. (You need two atoms of Oxygen to get Carbon Dioxide, hence the "di" part.)

covalent
Because since we give out carbon dioxide the plants use it to make photosynthesis so they give out the opposite kind of gas; oxygen.
When glucose is added to yeast in solution, the enzymes inside it turn the mixture into ethanol and carbon dioxide, so, for your question, carbon dioxide. It also respires normally (aerobically) and then too produces carbon dioxide.
