The relationship between molecular velocities and temperature is a direct relationship. Basically their relationship is directly proportional
Answer:
Yes, acetic acid could be used, but it would not be as effective as acetyl chloride or acetic anhydride. ... However, the acetic anhydride would still be reacting with an alcohol, so nothing changes in that respect. Also, the reaction would need to be done in basic solution.
Answer:
High pressure and low temperature, because particles are forced close together and moving slower, so intermolceular forces of attraction increase.
Explanation:
The properties of an ideal gas are explained by the kinetic-molecular theory. An ideal gas assumes there is no intermolecular attraction between the molecules. High pressure would make the particles closer together and interact more, going against the kinetic molecular theory that states there are large spaces between particles and no interactions between particles. Low temperature would make the particles slow which prevents them from overcoming the intermolecular attraction between particles.
<span>A polymer is made of more monomers
Amino acid is a monomer.
When you have more amino acids, it's a polymer (a protein)
So the answer is amino acid
the other 3 are polymers</span>
Answer:
3.18x10⁻³
Explanation:
The equilibrium of a weak acid can be written as:
And Ka can be expressed as:
- Ka=
<u><em>Keep in mind that [H⁺] = [A⁻]</em></u>.
We can<u> calculate [H⁺] from the pH</u>:
- [H⁺]==0.0158
Now we <u>compute the calculated [H⁺]</u> (and [A⁻]) <u>with the [HA] given by the problem</u>:
Ka = = 3.18x10⁻³
