A sample of Pb(C2H3O2)2 · x H2O has a mass of 1.20g was heated until 1.03 grams remains. Determine the formula of the hydrate, and name the hydrate.

distance, luminosity, brightness, radius, chemical composition, and temperature

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).
