<span>The correct answer is A. An electrolyte is a substance that conducts
electricity in solution because the solution has ions that electricity can flow. KNO3 and H2SO4 dissociates into potassium, nitrate, hydronium and sulfate ions when in solution therefore they are considered as electrolytes.</span>
Answer:
Number of peptide fragments resulting from cleaving with cyanogen bromide? A: Three peptide fragments
Number of peptide fragments resulting from cleaving with trypsin? A: Four peptide fragments
Which of these reagents gives the smallest single fragment (in number of amino acid residues)? A: CnBr, a dipeptide fragment consisting of AL (Alanine-Leucine)
Explanation:
Cyanogen bromide cleaves the methionine C-terminus, then we have a first fragment of 8 amino acids: DSRLSKTM, a second fragment of 15 aas YSIEAPAKLDWEQNM, and a last fragment of only 2 aas is produced, AL
Trypsin cuts the C-terminus of Arginine and Lysine, then we'll have a first fragment of 3 aas DSR, a second fragment consisting of also 3 aas LSK, a third fragment of 10 aas TMYSIEAPAK, and a last fragment of 9 aas LDWEQNMAL. All produced in three cut sites.
Explanation:
b and c are true statements
Answer:
0.220 M
Explanation:
<em>In the equivalence point, [H⁺] = [OH⁻]</em>.
This means we can use the formula C₁V₁=C₂V₂
Where
So we <u>compute the given data in the formula</u> to calculate C₂:
- 0.0500 M * 17.6 mL = C₂ * 4.00 mL
