The following is a limiting reactant problem: magnesium nitride is formed in the reaction of magnesium metal with nitrogen gas in this reaction: 3 mg(s) + n2(g) mg3n2(s) how many grams of product are formed from 2.0 mol of n2 (g) and 8.0 mol of mg(s)? show all calculations leading to an answer. list 3 indicators of a chemical change.

you would 3Mg+N2g and multiply that by 2.0+8.0

Examine the Nitrogen (blue), Carbon (black), Oxygen (Red) and Hydrogen (white) atoms, why do you think the holes are drilled where they are and differ from atom to atom

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).
