Consider the following diagram of a chemical reaction. A series of four increasingly more complex chemical structures. The first diagram shows that when heat is applied to R single bond O single bond O single bond R, it creates 2 R single bond O with 1 electron dot. The next structure brings in more complex structures and other atoms, such as H and C. This process continues until the final molecule has a long chain of six starting with R O and ending with C with a single electron dot. There are four single side chains, 3 P h and 1 H.
What is the product that is formed in this reaction?

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

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).
