Calcium carbonate
Yes. CaCO3 is a compound, and the term nonmetal does not properly apply to compounds.
Calcite is the most stable polymorphous form of calcium carbonate (CaCO3), a very common insoluble mineral salt. Though it contains Carbon and Oxygen it is not considered to be organic.
This is a very simple question that has a rather complicated answer. Marble is typically more than 95% calcium carbonate, perhaps even 99% calcium carbonate, and calcium carbonate is a compound. Many of the "fine chemicals" that you would find in jars in your school laboratory would have a similar purity to a good quality marble. So marble has a good claim to be recognised as a compound. However, if you look at a piece of marble, it has numerous very pretty stripes and blotches -- often known as "marbling" even. Clearly marble is not a homogeneous material. The small amount of various impurities in marble produce its very pretty appearance. So marble must also be recognised as a mixture.
Calcium hydroxide is an ionically bonded compound that dissolves in water to form a strong alkali; calcium carbonate is an ionically bonded compound that dissolves in water to form a weakly alkaline solution.
Carbon, Oxygen and Calcium.
The simpolest and most common compound is Calcium Carbonate (CaCO3). In a non-chemical environment it is referred to as limestone, chalk, or marble.
This compound is calcium carbonate - CaCO3.
Calcium carbonate contains 3 elements, calcium, carbon, and oxygen. The formula is CaCO3.
Calcium carbonate is the compound made from the elements oxygen, calcium, and carbon. It is commonly found in rocks, shells, and pearls.
Calcium carbonate
Calcium plus carbon plus oxygen plus oxygen plus oxygen equals calcium carbonate (CaCO3), which is a chemical compound that forms when calcium reacts with carbon and oxygen.
Calcium, carbon,and oxygen. It is the compound calcium carbonate, CaCO3
elements in a marble chip is not far fetched. They are: calcium, carbon and oxygen. otherwise known as CaCO3(note the three is below and not on the same line.
Perhaps a calcium carbonate like CaCO3
Chalk is primarily composed of calcium carbonate, which is a chemical compound. Calcium carbonate is made up of calcium, carbon, and oxygen atoms in a specific ratio, giving chalk its characteristic properties.
There is no compound CaCO. Since carbon and oxygen are non-metals, the only compounds they are likely to form with calcium are ionic compounds. So that would require making an anion out of carbon and oxygen. The only polyatomic anion that you can get from carbon and oxygen is carbonate, CO32-. So the calcium carbon oxygen that you might be referring to is calcium carbonate, CaCO3.
