Select the property that is not a characteristic of an ideal recrystallization solvent.
dybincka [34]

Answer:

(C) The recrystallization solvent should be nonvolatile.

Explanation:

Recrystallization is the separation technique which is used to purify the solid compounds in their crystal or amorphous form.

Some properties follow the recrystallization process as:

The solids are more soluble in hot solvent as compared to the solubility in the cold solvent.

The solvent must have lower boiling point and can be volatile easily.

The solvent should not react with the compound.

The impurities must be soluble in the cool solvent, so that only the pure product crystallizes.

Hence, Answer - C which is not an ideal characteristic.

The temperature inside your freezer is 0 degrees Celsius. You place a balloon with an initial temperature of 30 degrees C and a
blsea [12.9K]

Answer:

V=0.68L

Explanation:

For this question we can use

V1/T1 = V2/T2

where

V1 (initial volume )= 0.75 L

T1 (initial temperature in Kelvin)= 303.15

V2( final volume)= ?

T2 (final temperature in Kelvin)= 273.15

Now we must rearrange the equation to make V2 the subject

V2= (V1/T1) ×T2

V2=(0.75/303.15) ×273.15

V2=0.67577931717

V2= 0.68L
