A lab has 60 ml of a solution of uranium sulfate dissolved in water. based on the work done by the curies, how can the amount of

radioactivity be reduced? by adding more water to dilute the solution by removing sulfate ions by adding heat to raise the temperature by removing uranium ions

Water will not do much to stop the radiation; therefore, the amount of Uranium should be reduced to decrease the radioactivity.

Non electrolytes are Pentacarbon decahydride, Phosphorus pentachloride, Glucose.

<u>Explanation:</u>

Non electrolytes do not exist as ions in aqueous solution. Since it does not get dissociated into ions, these non electrolytes do not conduct electricity when it is dissolved or it is heated or melted.

Pentacarbon decahydride is a non electrolyte.

Magnesium chloride is an electrolyte.

Copper phosphate is an electrolyte

Sulfur trioxide is an electrolyte.

Aluminum oxide is an electrolyte

Phosphorus pentachloride do not get dissociated into its ions so it is a non-electrolyte.

Glucose gets dissolved in water but do not dissociate into ions, so it is a non electrolyte.

Lastly, Snape thinks we should try one more calculation. What is the retention factor if the distance traveled by the solvent fr
Neporo4naja [7]

Answer:

0.1 is the retention factor.

Explanation:

Distance covered by solvent ,d_s= 2.0 cm

Distance covered by solute or ion,d = 0.20 cm

Retention factor(R_f) is defined as ratio of distance traveled by solute to the distance traveled by solvent.

R_f=\frac{d}{d_s}

R_f=\frac{0.20 cm}{2.0 cm}=0.1

0.1 is the retention factor.
