calcium and oxygen
Carbon, hydrogen and oxygen are the only elements that make up sugars.
Calcium oxide (CaO) contain calcium and oxygen.
Elements
Atoms make up elements. groups of elements make up molecules. Groups of molecules form macromolecules (polymers) which make up cells.
Hydrogen, chlorine, fluorine and carbon are included in these molecules.
Calcium (Ca) and Oxygen (O) are the two elements that make up calcium oxide.
Calcium oxide, CaO: the ratio is 1.
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').
Carbon, hydrogen and oxygen are the only elements that make up sugars.
No, "cao" is not a binary compound. "Cao" is the chemical formula for calcium oxide, which is a compound composed of calcium and oxygen. Binary compounds are compounds composed of two different elements.
Common glass is made from sand, SiO2, Na2O and CaO. Concrete is a mixture of rocks (aggregate), sand, and water.
CaO
Calcium oxide (CaO) contain calcium and oxygen.
Yes, CaO is an ionic compound. It is composed of a metal (calcium) and a non-metal (oxygen) and forms an ionic bond between the two elements.
