Complete Question

The complete question is shown on the first uploaded image  

Answer:

The consumption of the reactant benzophenone and the production of  triphenylmethanol can be detected using their IR absorption spectrum

    This reaction is shown on the second uploaded image  

The reactant  benzophenone is a compound which contains a carbonyl functional group, and the stretching frequency of C=O bond has a high absorption at around 1680 \ cm^{-1} and frequency band of this wavelength is absent in triphenylmethanol.

in the same vain the product   triphenylmethanol is a compound which contains a hydroxyl (OH) functional group, and the stretching frequency of O-H bond has a high absorption at around 3474 \ cm^{-1} and frequency band of this wavelength is absent in benzophenone.

    To use infrared spectroscopy to show that the reaction is occurring is to show the disappearance of the 1680 \ cm^{-1}  frequency band which indictes the consumption of benzophenone and the appearance  3474 \ cm^{-1}  frequency band  which indictes the formation  of triphenylmethanol

Pharmacists sometimes measure medicines in the unit of "grains," where 1 gr = 65 mg. The label on a bottle of aspirin reads "Asp
viva [34]

Answer:

325mg of Aspririn

Explanation:

First you should note the information that the problem gives you:

- The bottle of Aspirin has 5gr (grains)

- 1gr(grain) = 65mg (miligrams)

Also, the problem is asking about how many aspirin are in 5 gr (grains), so you should use a conversion factor, as follows:

-First you should put the quantity you need to convert:

5grAspirin

-Then you write the denominator of the conversion factor that must have the same units that you want to convert, in this case gr:

5grAspirin*\frac{}{1grAspirin}

-Then you write the numerator with the units that you want to obtain and the numerical equivalence between the units, in this case:

5grAspirin*\frac{65mgAspririn}{1grAspirin}

-Finally you multiply numerators and divide by denominators:

5grAspirin*\frac{65mgAspririn}{1grAspirin}=325mgAspririn
