The one that looks red and is named after the god of war.
A chemical formula shows the elements in the compound and the ratio of atoms. For example, the chemicals formula for carbon dioxide is CO2 . In the carbon dioxide, there are always two oxygen atoms to every one carbon atom.
Which compound
It is not proper to say "Vapour is a proper name for the gaseous state of carbon dioxide" because carbon dioxide is not present as liquid under natural circumstances. The gaseous state of a substance ABOVE its own fluid (or dissolved in a solution) is called vapour of that particular compound.
It is to make sure that carbon dioxide is present or not present in the experiment.
The planet Mars.
Carbon dioxide is a covalent compound, it contains no ions.
The one that looks red and is named after the god of war.
Although Carbon is present in all organic compounds, carbon dioxide is not considered to be an organic compound. Nor are carbonates.
There is no other substance present and so it is a compound a pure substance just as NaCl - salt is.
A chemical change, since there is carbon dioxide produced, a compound not previously present.
Carbon Dioxide is present in unpolluted air. Methane (animals grazing literally fart this out) is also present and Nitrogen oxides formed when lighting strikes. The electrical discharge is high enough to cause oxygen and nitrogen to combine. It is basically a natural fertilizer In unpolluted air these compounds are present at levels of about 390 parts per million, 1.8 parts per million, and 1 part per billion respectively. The most abundant and most important compound in unpolluted air is ... water vapour -- present at levels which vary between about 0.1% and 5%, depending on temperature and humidity.

Some of the words and parts of words that tells us that oxygen is present in a compound are oxide, dioxide, trioxide, etc.; peroxide; alcohol; ether; ester; carboxylic acid and all the names of specific carboxylic acids; oxyacid; and all anion names ending in -ite or -ate.
