Mercury (Hg) is present in trace amounts in coal, ranging from 50.0 to 200.0 ppb. A typical power plant burns 1.49 million tons
faust18 [17]

Answer and Explanation:

To calculate this, simply use an equality of proportions:

50 particles  :  1 billion particles = <em>x</em> tons  :  1.49 million tons

The value of <em>x</em> can be solved for by multiplying the ratio on the left by the value 1.49 million / 1 billion:

So, <em>x</em> = (50)(0.00149) tons = 0.0745 tons

Then, do the same thing for the larger concentration:

<em>x</em> = (200)(0.00149) tons = 0.298 tons

This set contains the spectra of benzil, biphenyl, and bibenzyl, three compounds used in the melting point experiment. Using you
murzikaleks [220]

Answer:

Spectrum 1- Biphenyl

Spectrum 2 - Benzil

Spectrum 3 - Bibenzyl

Explanation:

<u>For Benzil: </u>

<u> </u>The Spectrum -  2  shows this compound.The C=O and C-H bond stretching observed at following values.

C=O \,at\,1657cm^{-1}

C=H \,at\,3063cm^{-1}

<u> For Biphenyl: </u>

<u> </u>Spectrum -  1  shows this compound.

There are stretching vibrations from 3061, 3032\,and \,1597 -1428cm^{1} due to C-H stretching and C-C stretching respectively of aromatic ring only.

<u>For Bibenzyl: </u>

Spectrum - 3  shows this compound

There are stretching vibrations at 3057,3026 and 1598 - 1449cm^{-1} due to C-H stretching and C-C stretching of aromatic ring.

Along with this, stretching vibrations at 2943 - 2917 cm^{-1}due to C-H of alkyl.
