What will be the effect on the solubility of BaF2 if the following changes are made: increasing temperature; adding NaF; adding

borishaifa [10]

In BaF₂ the solubility will decreases on adding NaF

the solubility will increases on adding HCl

<h3>SOLUBILITY OF BARIUM FLUORIDE</h3>

Increase in temperature will increase the solubility of the solid.
By adding NaF - decrease the solubility of BaF₂
By adding HCl - increase the solubility of BaF₂

<h3>BARIUM FLUORIDE</h3>

It is colourless solid that occur as rare mineral
It is corroded by moisture
It is used in window of IR spectroscopy

Hence the barium fluoride the solubility decreases on adding NaF and increases on adding HCl.

Which step of mitosis involves the nucleus splitting and nuclear membranes forming around each new nucleus?

guapka [62]

“telophase” because it’s the only step that actually involves the cell to physically split, and it also involves the forming of a nuclear membrane

Hope this helps :)

Anthony needs to make a solution with a concentration of 2.5m. He begins with 2.0 iters and a 8.0M solution. What final volume d

FrozenT [24]

Answer:

The final volume is 6.4 L.

Explanation:

Dilution is reducing the concentration of a chemical and is achieved by adding more solvent to the same amount of solute. In other words, dilution is the procedure that is followed to prepare a less concentrated solution from a more concentrated one, and it simply consists of adding more solvent.

In a dilution the amount of solute does not vary, and as only more volume (and mass) of solvent is being added, the concentration of the solute decreases.

In a dilution the expression is used:

Ci*Vi = Cf*Vf

where:

Ci: initial concentration
Vi: initial volume
Cf: final concentration
Vf: final volume

In this case:

Ci: 8 M
Vi: 2 L
Cf: 2.5 M
Vf: ?

Replacing:

8 M* 2 L= 2.5 M* Vf

Solving:

$Vf=\frac{8 M* 2 L}{2.5 M}$

Vf=6.4 L

<u><em>The final volume is 6.4 L.</em></u>
