Calcium carbide (CaC 2 ) reacts with water to produce acetylene gas, C 2 H 2 , and calcium hydroxide, Ca(OH) 2 . Write the balanced equation for this reaction. Calculate the volume of acetylCalculate the mole fraction of each solute and solvent in the solution of 46.85 g of codeine, C 18 H 21 NO 3 , in 125.5 g of ethanol, C 2 H 5 OH. ene produced at 27 °C and 756 torr from 0. 075 mol CaC 2 and excess H 2 O.

personal, she chose to do it.

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).
