Active transport, because it is using energy, and it is taking the food from where there is not much to where there is a lot.

As water is added to a 0.10 M NaCl aqueous solution, the conductivity of the resulting solution

andrew11 [14]

The more water added the lower the conductivity. The Na+ and Cl- ions allow the solution to be conductive. The lower the concentration, the less conductive the solution will get until it is not conductive at all.

SrCl2(aq)+2NaF(aq)⟶SrF2(s)+2NaCl(aq)

aleksandr82 [10.1K]

Answer:

637.636 mL of NaF
0.7014 moles of SrF2

Explanation:

$C_{1}V_{1}$ = $C_{2}V_{2}$

Where 1 and 2 represent NaF and SrCl2 respectively; and C and V ae concentration and volume.

0.110 × V1 = 0.420 × 167

<em>V1 = </em> $\frac{70.14}{0.110}$ <em> = 637.636 mL ≈ 0.638 L.</em>

Mole ratio of SrF2:

mole ratio of SrCl2 : SrF2 is 1 : 1 (also, conc × vol = no. of moles )

<em>∴ moles of SrF2 = 0.7014.</em>
