Joe student reacts aqueous solutions of Na, co, and Ca(NO3)2. Calcium carbonate and sodium nitrate are produced. He wishes to collect the precipitate from this reaction.
If Joe starts with 10.6 g of Na, co, what mass of CaCO3, should he expect to collect?
+ Ca(NO3)2taq) → NaNO3(aq) + CaCO3(0)
Na, CO3(aq)

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).

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
