Answer:

The correct option is: b. the side chain

Explanation:

Amino acids are biomolecules that contain an alpha-carbon (α-C) attached to two functional groups- carboxyl group (-COOH) and amine group (-NH₂), and an organic side chain (-R).

The carboxyl and amine functional groups are common in all amino acids but the side chain is distinctive to each amino acid.

Thus the amino acids can be easily classified on the basis of the properties of this organic side chain.

Therefore, the various amino acids have different side chains.

What is the energy in joules of one photon of microwaveradiation with a wavelength 0.122m?

pentagon [3]

Answer: The energy of photon is $162.93\times 10^{-26}J$

Explanation:

The relation between energy and wavelength of light is given by Planck's equation, which is:

$E=\frac{hc}{\lambda}$

where,

E = energy of the light = ?

h = Planck's constant = $6.626\times 10^{-34}Js$

c = speed of light = $3\times 10^8m/s$

$\lambda$ = wavelength of photon = 0.122 m

Putting values in above equation, we get:

$E=\frac{(6.626\times 10^{-34}Js)\times (3\times 10^8m/s)}{0.122m}\\\\E=162.93\times 10^{-26}J$

Hence, the energy of photon is $162.93\times 10^{-26}J$

marysya [2.9K]

A strong acid- strong base titration is performed using a phenolphthalein indicator. Phenolphtalein is chosen because it changes color in a pH range between 8.3 – 10. It will appear pink in basic solutions and clear in acidic solutions. ... It is known as the titrant.
