Looking up one rainy afternoon from lab notebook, your friend Brian (an expert chemist) says this: "Metal sulfides roasted with oxygen produce the corresponding oxide and sulfur dioxide gas."
Using Brian's statement, and what you already know about chemistry, predict the products of the following reaction.
Be sure your chemical equation is balanced!

i believe it is-

d.) gravity pulled particles of dust and gas together to form planets.

its first and third is your answer i did the qustion the fourth isnt right

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).
