Hardness is 4.5-5, specific gravity 2.85, luster vitreous to pearly, color ranges from colorless to white with green, brown, or pink tints, and cleavage is perfect in three directions. Like calcite, dolomite occurs in virtually all geologic settings: in igneous rocks as carbonatite, in metamorphic rocks as marble, and in hydrothermal deposits.

Let's balance this equation using the inspection method. First, we set all coefficients to 1: 1 CaMg (CO 3) 2 = 1 MgO + 1 CaCO 3 + 1 CO 2. For each element, we check if the number of atoms is balanced on both sides of the equation. Ca is balanced: 1 atom in reagents and 1 atom in products. Mg is balanced: 1 atom in reagents and 1 atom in products.
