Explanation:

Photosynthesis is the process by which green plants manufacture their food using carbon dioxide and water in the presence of sunlight.

It is expressed using the equation below;

      6CO₂   +   6H₂O     →      C₆H₁₂O₆  +  6O₂

         reactants                      products

1. Compounds consumed are carbon dioxide and water.

2. Product is glucose and oxygen.

3. Most organism obtain their nourishment directly and indirectly from photosynthetic activities.

Plants are the producers of food in the ecosystem. If the process of photosynthesis does not occur, there is no way other organisms will obtain their own nourishment.

Q. Calculate the number of atoms in each of the following (i) 52 moles of Ar (ii) 52 u of He (iii) 52 g of He​
andreyandreev [35.5K]

\huge\mathfrak\red{❥︎AnSweR:-}

(i) 1 mole of Ar =6.022×10^23

atoms of Ar

52 mol of Ar=52×6.022×10 ^23

atoms of Ar =3.131×10 ^25 atoms of Ar

(ii) Atomic mass of He = 4amu

Or

4amu is the mass of He atoms = 1

Therefore 52 amu is the mass of He atoms=0.25×52=13 atoms of He

(iii) Gram atomic mass of He = 4g

Or

4g of He contains =6.022×10 ^23

atoms

Therefore 52 g of He contains=

6.022×10 ^23/4×52 =7.83×10 ^24 atoms

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.
