As given in the question, it is two separate elements.
However, the two elements do combine to form the compound 'Calcium oxide', with the formula ' CaO'.
CaO ( calcium oxide) is commonly known as 'Lime/Quicklime').
The formula for the binary compound of calcium and oxygen is CaO. This compound is known as calcium oxide.
The compound calcium chlorate contains the elements calcium (Ca), chlorine (Cl), and oxygen (O).
Calcium sulfate is a compound. It is composed of the elements calcium, sulfur, and oxygen chemically bonded together.
Calcium oxide is formed when calcium reacts with oxygen.
Calcium carbonate contains 3 elements, calcium, carbon, and oxygen. The formula is CaCO3.
The formula for the binary compound of calcium and oxygen is CaO. This compound is known as calcium oxide.
It would be a compound, made of Calcium and Oxygen.
The compound calcium chlorate contains the elements calcium (Ca), chlorine (Cl), and oxygen (O).
This compound is calcium carbonate - CaCO3.
calcium
Calcium sulfate is a compound. It is composed of the elements calcium, sulfur, and oxygen chemically bonded together.
Calcium oxide is formed when calcium reacts with oxygen.
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.
If calcium and oxygen are in the same container, they would combine to form calcium oxide, which is a compound. Calcium and oxygen individually are elements, but when combined in a fixed ratio, they form a compound with different properties from the elements themselves.
Calcium carbonate
None. Calcium and oxygen are both elements that can combine to form the compound calcium oxide, CaO.
