How many moles of aluminum can be produced from 1.30 moles of aluminum oxide? We need the mole ratio of Al2O3 to Al. We can find mole ratios in balanced chemical equations.
Write the equation below:

Mole ratio: For every ___ moles of aluminum oxide that decompose, ___ moles of aluminum are produced.
Use this ratio as a conversion factor to solve the problem.

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).

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
