Which is an important step in the alternate method for balancing equations in redox reactions? a) indicating the types of bonds found in the molecules. b) determining the speed at which reactions take place. c) determining the half reactions of chemical equations. d) indicating the temperature at which the reaction occurs.

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).
