Aluminum reacts with aqueous copper (ii) chloride in a single displacement reaction to produce aluminum chloride and solid copper. how many moles of copper (ii) chloride are required to react fully with 0.357 mol aluminum?

2Al + 3CuCl2 > 3Cu + 2AlCl3

from reaction 2 mol 3 mol

given 0.357 mol x mol

x= 0.375*3/2 = 0.563 mol CuCl2

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).
