What is the energy of a photon using the given frequency and Planck's
nydimaria [60]

Answer:

Energy of photon is 34.45 ×10⁻¹⁹ J.

Explanation:

Given data:

Frequency of photon = 5.2×10¹⁵ s⁻¹

Plancks constant = 6.626×10⁻³⁴ Js

Energy of photon = ?

Solution:

Formula:

E = h.f

by putting values,

E =  6.626×10⁻³⁴ Js × 5.2×10¹⁵ s⁻¹

E = 34.45 ×10⁻¹⁹ J

Thus, energy of photon is 34.45 ×10⁻¹⁹ J.

Write the structure of a D-aldohexose that gives a meso compound on treatment with NaBH4 in water.
soldier1979 [14.2K]

Explanation:

Meso compounds are optically inactive stereoisomers. Despite of having chiral carbon, they do not show  optical activity because it has a plane of symmetry in its structure itself. It is superposable on its mirror image.

Aldo sugars on reaction which reducing agents such as , NaBH₄ reduces the carbonyl group in the sugar to alcohol and gives corresponding alditol.

<u>The D- aldohexose which on reduction gives a meso alditol are allose and galactose. </u>

<u>The structure is shown in the image below. Thus, in allitol and galactitol formed have internal plane of symmetry which makes the optically inactive.</u>

If a chemical reaction such as photosynthesis begins with 6 atoms of carbon C , how many atoms of carbon C should be in the prod
pochemuha
B. 6 atoms of carbon C
I would think this is the answer, because one can't just delete or add atoms; otherwise, the equation would be unbalanced. This also abides with the Law of Conservation of Mass.

Plus, I also came to that conclusion because if we look at the net equation of photosynthesis:
6C O_{2} + 6H_{2}O ––> C_{6}H_{12}O_{6} + 6O_{2}
The number of Carbon atoms is 6 on both the reagent's side and the product's side.
