The Law of Conservation of Mass states that during a chemical reaction, mass/matter is not Because of this law, there must be exactly the same number and kind of on each side of a chemical equation. To check if an enantion is balanced or not simply count the number of atoms of each element on the reactant side of the equation and check to see if there are the same number of atoms of each element on the ___side of the equation. If so, it is balanced.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
