Oxide is not any particular substance. The term oxide can refer to one of two things:
1: The oxide ion (O2-) which needs some sort of positive ion to balance the charge.
2: A binary compound containing oxygen and another element.
Neither is an example of a mixture.

Hetero means different. Homo means the same.
Since Calcium Carbonate always has the same elements in it, it is homogeneous.

Is cement a heterogeneous mixture?
Mortar is heterogeneous. You can clearly tell the different parts of the mixture apart from one another (calcium carbonate and sand), thus, it is a heterogeneous mixture. The two particles are not chemically combined, but simply mixed together. Heterogeneous Mixture.
Is chalk is homogeneous or heterogeneous?
Chalk consists of calcium carbonate. It would be a heterogeneous mixture if colours were added to it.
Is calcium carbonate a homogeneous or heterogeneous mixture?
Neither of both because it is NOT a mixture at all; it's a (pure) compound (one kind of molecules)
Is calcium heterogeneous homogeneous mixture?
Calcium is an element. It is neither.
Is calcim carbonate a element compound or mixture?
Calcium Carbonate is a compound and an element. However, it is not a mixture. If it is a compound or a element, then it can not be a mixture

Is calcim carbonate a element compound or mixture?
Calcium Carbonate is a compound and an element. However, it is not a mixture. If it is a compound or a element, then it can not be a mixture
Is marble a heterogeneous or homogeneous mixture or pure substance?
Marble is a heterogeneous mixture. This means the rock is made out of two different mixtures, you can tell this because of the swirls that occur in it.
What compound can magnesium be found in?
Dolomite limestone is a mixture of calcium carbonate and magnesium carbonate.
Is sand a compound homogenous mixture heterogenous mixture?
Sand is a mixture (but it is important to mention that some times sands formed from silicon dioxide, calcium carbonate, lava, shells may be not considered as mixtures); sands may be homogeneous but also heterogeneous.
Is aluminum oxide an heterogeneous mixture?
Pure quicklime is calcium oxide, which is a compound, not a mixture. Commercially available supplies may be mixtures, as they are made from naturally occurring limestone, which may not be pure calcium carbonate. However such impure mixtures are usually pretty homogeneous.
What kind of mixture is chalk?
Chalk is not a mixture it is a chemical compound called Calcium carbonate.
How calcium carbonate can be removed from the mixture?
Calcium carbonate can be removed from a mixture by using a process called filtration or decantation. In filtration, the mixture is passed through a filter paper, which allows the liquid to pass through while retaining the solid calcium carbonate. In decantation, the mixture is left undisturbed to allow the solid calcium carbonate to settle at the bottom, and the liquid can then be carefully poured off.
What do carbon minerals contain?
Most carbonate minerals are either calcium carbonate (limestone) or a mixture of calcium carbonate with magnesium carbonate (dolomite). However other metals can also combine with carbonate to produce much rarer carbonate minerals.
