Answer:
The correct answer is 1 x 10⁻⁵
Explanation:
In order to solve the problem, we can use the Henderson-Hasselbach equation to find the ratio alanine-COOH/alanine-COO⁻ (amino acid species with carboxylic acid protonated) and the ratio alanine-NH₂/alanine-NH₃⁺ (amino acid species with amino group neutral):
Henderson-Hasselbach equation:
<u>For carboxylic acid group (pKa= 3) at pH 7</u>:
We need the ratio of species with <u>protonated</u> carboxylic acid group, so we need the inverse:
<u>For amino group (pKa= 8) at pH 7</u>:
Finally, to find the ratio of neutral species we multiply the ratios:
X = 10⁻⁴ x 10⁻¹= 10⁻⁵
Answer:
Maybe the Salad
Explanation: I mean it's lunch time and he forgot it home so if it was really important don't you think he would go home. The salad is a light meal compared to a pork chop and chips and that also sounds like a dinner choice to me. So salad would be the best option for lunch
