Magnesium,carbon oxygen.
Dolomite limestone is a mixture of calcium carbonate and magnesium carbonate.
Calcium, oxygen, and carbon are common elements found in carbonate minerals. Other elements such as magnesium, iron, and manganese can also be present depending on the specific mineral. These elements combine with carbonate ions to form minerals such as calcite (calcium carbonate) and dolomite (calcium magnesium carbonate).
Magnesium carbonate is a compound. It consists of the elements magnesium, carbon and oxygen chemically combined. As a rule of thumb anything with two or more elements chemically bonded together is a compound.
The chemical formula* for magnesium carbonate is MgCO3. *Note that compounds have chemical formulas; elements have chemical symbols.
Magnesium carbonate contains magnesium atoms and carbonate ions. These two elements combine chemically to form a compound with a specific chemical formula.
I assume you mean MgCO3, not MgCo3 (the first is magnesium carbonate). Be careful when writing CO, because Co is cobalt, and CO is carbon and oxygen. Mg is Magnesium, C is carbon and O is oxygen. Therefore the elements present are magnesium, carbon and oxygen.
Mainly Calcium and magnesium carbonate.
The formula for carbonate is CO3. This means there are 2 elements in carbonate; oxygen and carbon.
Magnesium carbonate is a mineral salt composed of magnesium, carbon, and oxygen. It can be found in nature in the form of magnesite ore or as part of different minerals like dolomite. Commercially, magnesium carbonate is often produced through the reaction of magnesium chloride with sodium carbonate.
Magnesium commonly bonds with elements such as oxygen (O), sulfur (S), and carbon (C) to form compounds like magnesium oxide (MgO), magnesium sulfate (MgSO4), and magnesium carbonate (MgCO3).
