When deployed, car air bags rapidly inflate as sodium azide, NaN₃, decomposes into it's component elements, given by the following reaction: 2 NaN₃-> 2 Na + 3 N₂ a) How many grams of NaN₃ are required to form 5 grams of nitrogen
gas? b) How many grams of sodium are produced from that amount of sodium azide? (use your answer from 4a)

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

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).
