Identify how IR spectroscopy might be used to monitor the progress of the following reaction. A. The reactant should not have signals at 1650 cm1 or 3100 cm1, while the product(s) should have such signals. B. The reactant should have a broad signal from 3200 3600 cm-1, while the product(s) should lack this signal and instead should have a signal at ~1720 cm1.C. The reactant should have signals at 1650 cm-and 3100 cm-1, while the product(s) should not have either of these signals. D. The reactant should have signals at 1650 cm-1 and 3100 cm-1, while the product(s) should both have a signal at ~1720 cm-1.

idk what the question is about

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

50.23 i believe is correct but don't quote me on that.
