Answer:
Explanation:
Molal freezing point depression constant of butanol Kf = 8.37⁰C /m
ΔTf = Kf x m , m is no of moles of solute per kg of solvent .
mol weight of butanol = 70 g
235.1 g of butanol = 235.1 / 70 = 3.3585 moles
3.3585 moles of butanol dissolved in 4.14 kg of water .
ΔTf = 8.37 x 3.3585 / 4.14
= 6.79⁰C
Depression in freezing point = 6.79
freezing point of solution = - 6.79⁰C .
Chlorine would become a liquid. Its boiling point is around -34 Celsius so at any temperature below that it would be liquid.
C or A I may be incorrect but those are what I think it is
So, to determine the number of neutrons in atom, we only have to subtract the number of protons from the mass number. Take note that the nucleus of an atom is composed of protons and neutrons. And the number of particles present in the nucleus is referred as mass number (Also, called as atomic mass).
Answer:
The answer is B, Alanine would be in the interior and serine would be on the exterior of the globular protein.
Explanation:
To further explain, the nature of solubility of side chain determines the position of the amino acid in the globular protein.
The hydrophilic amino acid such as serine are on the outside of the globular protein while the hydrophic amino acids such as leucine and alanine are on the interior of the globular protein.
This is why Alanine would be in the interior and serine would be on the exterior of the globular protein.
Cheers!
