carbon dioxide
Helium does not combine with other elements and pure helium will not have carbon dioxide in it.
glucose
Plants don't combine hydrogen and carbon dioxide directly; if they did (and did so in a 1-to-1 ratio), the result would be formaldehyde. Instead, plants combine carbon dioxide and water in such a way as to produce carbohydrates (particularly glucose) and oxygen in a multi step complex synthetic process.

They don't react.
Urea!
Carbon dioxide is the product of a combustion reaction.
Soda water.
Carbon and oxygen combine to form carbon dioxide, CO2, during the combustion of fuel.
Carbon is combined with oxygen forming 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.)
glucose
True
Sugar and oxygen.
