Answer:
The energy of the particles increase and the molecules move more quickly.
Explanation:
The molecules are moving from a solid (barely moves, molecules close together) to a liquid (molecules slide past each other and take any shape), so molecules are moving more and have more energy
Answer:
Equilibrium will lie to the right.
Explanation:

That means HF is stronger acid than
.
Alternatively, it can be said that
is a stronger base than
.
Therefore HF readily gives proton to
to form
and
than the reverse reaction.
So, the equilibrium will lie more towards the right i.e. towards formation of
and
.
Answer:

Explanation:
Hello there!
In this case, given the neutralization of the acetic acid as a weak one with sodium hydroxide as a strong base, we can see how the moles of the both of them are the same at the equivalence point; thus, it is possible to write:

Thus, we solve for the molarity of the acid to obtain:
