Answer:
Esters are both inorganic and organic acids .... Regarding the second question, it is believed that it is carried out in this way in order to recognize the C-terminal amino acid in a peptide within a protein
Explanation:
The explanation of this question is according to what was interpreted in the question, since it is considered that it is poorly written ...
What happens in this chemical reaction is that it first becomes an ester (organic or inorganic acid) so that it is later recognized in the complex peptide structure.
<span>The chlorine isotope with 18 neutrons has an abundance of 0.7577 and a mass number of 35 amu. To calculate the averageatomic mass, multiply the fraction by the mass number for eachisotope, then add them together.</span>
The answer is C, I hope this answers your question :)
Answer:
The concentration of is 1.48 × M
The absolute uncertainty of is ±0.12 × M
The concentration of is written as 1.48(±0.12) × M
Explanation:
The pH of a solution is given by the formula below
pH =
∴
where is the concentration
From the question,
pH = 8.83±0.04
That is,
pH =8.83 and the uncertainty is ±0.04
First, we will determine from
× M
× M
The concentration of is 1.48 × M
The uncertainty of ( ) from the equation is
× ×
Where is the uncertainty of
is the uncertainty of the pH
Hence,
= 2.303 × 1.4791 × × 0.04
= 1.36 × M
= 0.12 × M
Hence, the absolute uncertainty of is ±0.12 × M
