In order to balance an equation, we apply the principle of conservation of mass, which states that mass can neither be created nor destroyed. Therefore, the mass of an element before and after a reaction remains constant. Here, the balanced equation becomes:
4Al + 3O₂ → 2Al₂O₃
The coefficients are 4, 3 and 2.
Answer:
The corect answer is c) naturally occurring; solids

Minerals exists as solid substances in nature consisting of one or more element chemically combined together formiming compounds with definite composition. As mentioned earlier single elements can form minerals and examples of single element mineral are Silver, Carbon and Gold which are found in nature in their pure form and are mined.
Minerals are normally found in rocks, which may contain one ore more different types of minerals
The carbon cycle involves the circulation of carbon dioxide (CO2<span>) from the atmosphere into plants and other living organisms; the transfer of carbon from these organisms into other temporary storage pools, living or nonliving, containing organic and </span>inorganic<span> carbon compounds; and the return of CO</span>2<span> to the atmosphere </span>
