I think the correct answer is the first option. The analyte was an acid but and the titrant is a base since from the graph the initial pH of the solution is at an acidic pH when there is still no titrant added.
Answer
36.45 u; X = Cl
Explanation:
The atomic mass of X is the <em>weighted averag</em>e of the atomic masses of its isotopes.
We multiply the atomic mass of each isotope by a number representing its relative importance (i.e., its percent of the total).
Set up a table for easy calculation
.
0.7577 × 34.969 u = 26.496 u
0.2423 × 36.965 u = <u> 8.9566 u
</u>
TOTAL = 36.45 u
X = Cl
Answer:
water spreads the spicy taste around your mouth, while milk does not and it helps the hot taste go away.
Explanation:
Answer:
Polypeptide
Explanation:
A polypeptide contains 10 or more amino acids join together by a covalent bond called peptide bond.
A peptide bond is formed when when an alpha carboxyl group of one amino acid react with alpha amino group of another amino to form a CO-NH bridge.
Covalent linkage of two amino acids residue from a dipeptide, 3 amino acids residues from a tripeptide. Continuous polymerization of 10 or more amino acid is called a polypeptide. While when there are 50 or more amino acids join together by peptide bonds it is called protein.
