a mixture of sodium bicarbonate and sodium carbonate is heated strongly in a crucible for 15 minuites. the respective mass are recorded below. the equation for the decomposition of sodium bicarbonate is 2NaHCO3=Na2CO3+CO2+H2O. determine the mass % of Na2CO3 in the mixture

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).
