As you go down group 7 the melting point of the elements will increase, this is because as you go down the group you are gaining an electron shell and the molecule will become bigger. This increase in size means that there will be an increase in the intermolecular forces as well.

So the order would be NF3, NBr3, NI3.

Hopefully this helps!

For which salt is the aqueous solubility most likely to change by changing the pH of the solution?
Hoochie [10]

The salt whose aqueous solubility will most likely to change the pH of the solution is CaF2(aq).

The pH of a salt solution depends on the nature of the acid and base that forms the salt.

  • Salt of a weak acid and a strong base yields a basic solution
  • Salt of a strong acid and a weak base yields an acidic solution
  • Salt of a strong acid and a strong base yields a neutral solution.

Since HF is a weak acid, its salt CaF2 will be slightly basic when dissolved in water hence the pH of the solution is altered.

AveGali [126]

Answer:

\huge\boxed{\sf m = 180\  g}

Explanation:

<u>Given:</u>

Density = ρ = 0.8 g/cm³

Volume = V = 225 cm³

<u>Required:</u>

Mass = m = ?

<u>Formula:</u>

m = ρV

<u>Solution:</u>

m = (0.8)(225)

m = 180 g

\rule[225]{225}{2}

Hope this helped!
