Slader A Methanol (CH3OH) burns with air. The product gas is analyzed, and the laboratory report gives only the following percentages on a dry molar basis: 7.1% CO2, 2.4% CO, 0.84% CH3OH. Assuming the remaining components consist of O2 and N2, determine a) the percentages of O2 and N2 in the dry molar analysis. b) the percent excess air.

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).

since electrons are negative the answer is neagtaive
