Discuss the differences observed in the IR and NMR spectra of 4-cyclohexene-cis-1,2-dicarboxylic anhydride and of 4-cyclohexene-cis-1,2-dicarboxylic acid that areconsistent with the conversion of an anhydride to a diacid function in this experiment.(2 pts)Discuss the differences observed in the IR and NMR spectra of 4-cyclohexene-cis-1,2-dicarboxylic anhydride and of 4-cyclohexene-cis-1,2-dicarboxylic acid that areconsistent with the conversion of an anhydride to a diacid function in this experiment.(2 pts)

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).

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
