Which of the four substance below is a compound based on the information in the table? The table below shows the chemical symbols for some common elements.

The correct answer to this question is CO. CO is a compound of carbon and oxygen. A compound itself is a chemical that is formed from atoms that are taken from two different elements. Chemical bonds join the particles together. Their bond is so strong that they stick together and behave as one.

A chemical compound can be a liquid, solid, or a gas. CO is a gas. Another example is H20, which is a liquid. Compounds can be made naturally through plants or synthetically through a scientist, making them in a lab. When it is made synthetically, it is called synthetic chemicals.

Co is the compound, and it is a compound of carbon and oxygen. Hydrogen is not a compound, helium is an unreactive element, and it’s believed that helium compounds do not exist at all, silicon is not a compound it is a chemical element, and iron is a chemical element.

Co, which is carbon and oxygen, would be a compound because it’s two separate elements combined to make carbon monoxide, which is a gaseous compound. Not suitable to breathe it and it is usually present in automobile exhaust.
