Fynjy0 [20]

Answer:

1. Both

2. Acid

3. Acid

4. Base

5. Acid

6. Neither

7. Neither

8. Base

9. Acid

Explanation:

In Chemistry, a chemical compound can be either a base or an acid.

An acid reacts with metals to produce bubbles of hydrogen gas and it also reacts with carbonates while a base feels slimy to the touch. They both can change the color of a litmus paper.

Base has a sour taste while acids have a bitter taste (please do not use this characteristic to test for an acid in the laboratory)

Alpha helices are a type of secondary structure in proteins. What is the length of a 33.0 kDa single‑stranded α‑helical protein
WARRIOR [948]

Answer:

450 Å

Explanation:

The amino acids in an α-helix are arranged in a right-handed helical structure where each amino acid residue corresponds to a 100° turn in the helix, and a translation of 1.5 Å (0.15 nm) along the helical axis

Mass of protein= 33.0 kDa

33.0 kDa ×(1000Da/kDa) × ( 1 residue/ 110 Da)

=33.0 ×1000 × 0.0091

= 300 residues

300 residues × (1.5Å /residue)

=450 Å
