Calcium chloride is a compound, not an element or a mixture. It is composed of calcium and chlorine atoms chemically bonded together in a fixed ratio.
Calcium bromide is a compound because it is composed of calcium and bromine elements that are chemically bonded together in a fixed ratio.
Calcium sulfate is a compound. It is composed of the elements calcium, sulfur, and oxygen chemically bonded together.
Calcium is chemically reactive, especially with water and oxygen. It reacts vigorously with water to form calcium hydroxide and hydrogen gas. In the presence of oxygen, calcium forms a protective oxide layer on its surface.
Calcite is not an element. It is a mineral which is made up of the elements calcium, carbon, and oxygen.In chemistry it is known as the compound calcium carbonate, CaCO3
Calcium oxide, or quicklime, can be decomposed chemically into its components, calcium and oxygen. Calcium is an element and cannot be decomposed chemically.
Yes, calcium chloride is a compound because it is made up of at least two elements chemically bonded together.
Calcium carbonate is a pure substance because it has a fixed composition of calcium and carbonate ions. However, it is not an element because it is a compound made up of multiple elements (calcium, carbon, and oxygen) chemically bonded together.
Calcium sulfate is a compound because it is formed from the elements calcium, sulfur, and oxygen chemically bonding together in a specific ratio.
Calcium and oxygen (calcium oxide) are present in quick lime.
Calcium is an element. (Ca on the periodic table).
Carbon (C)
