Explanation:
There are non-polar side chains also present in alanine. And, these non-polar side chains are involved in some hydrophobic interactions in active sideand then it changes into polar amino acid glutamate that will destroy the hydrophobic interaction.
Whereas in glycine there is only hydrogen present in the side chain therefore, it will not affect much.
Answer:
The correct answer is - butanoic acid
Explanation:
An empirical formula is the general formula or base formula that is the simplest positive integer ratio of atoms present in a compound. The empirical formula is specific to specific compounds or types of compounds.
Among the given options, the empirical formula C2H4O is butanoic acid as the molecular formula of butanoic acid is - C4H8O2 which is multiple of C2H4O. Other compounds have different than this empirical formula.

Answer:
pH = 2,4
Explanation:
pH is defined as a measure of acidity or alkalinity of a solution based on H⁺ concentration
The HCl dissociates in water thus:
HCl → H⁺ + Cl⁻
That means that moles of HCl are the same than H⁺.
0,35gHCl
= 9,6x10⁻³ moles HCl ≡ moles H⁺
H⁺ molarity is: 
= 3,84x10⁻³M
As pH = -log [H⁺]
<em>pH = 2,4</em>
I hope it helps!
