Answer:

Fractional column is an essential item used in distillation of liquid mixtures so as to seperate the mixture into its component parts, or fractions based on the differences in volatilities.

Explanation:

A tall, horizontally subdivided or packed container for fractional distillation in which vapor passes upward and condensing liquid flows downward. The vapor becomes progressively enriched in more volatile components as it ascends, and the less volatile components become concentrated in the descending liquid, which can be drawn off.

How much heat is needed to vaporize 10.00 grams of water at 100.0°c? the latent heat of vaporization of water is 2,259 j/g. 22.5
puteri [66]

The correct option is:

The latent heat of vaporization of water is given by option D. 22,590J

Latent heat of vaporization:

Latent heat of vaporization is energy required to change 1 kg of liquid to gas at atmospheric pressure at its boiling point.

Also, Latent heat is the energy released or absorbed during a phase change.

Energy released during phase change is Exothermic process.

Whereas energy absorbed during phase change is Endothermic process.

Q=mL

Q= Latent heat

m= mass= 10 g

L= Latent heat of vaporization= 2,259 J/g

Putting the values in the above equation:

Q=10*2259

Q=22590 L

How many moles of PC15 can be produced from 51.0 g of Cl2 (and excess P4)?
slava [35]

Answer:

0.287 mole of PCl5.

Explanation:

We'll begin by calculating the number of mole in 51g of Cl2. This is illustrated below:

Molar mass of Cl2 = 2 x 35.5 = 71g/mol

Mass of Cl2 = 51g

Number of mole of Cl2 =..?

Mole = Mass /Molar Mass

Number of mole of Cl2 = 51/71 = 0.718 mole

Next, we shall write the balanced equation for the reaction. This is given below:

P4 + 10Cl2 → 4PCl5

Finally, we determine the number of mole of PCl5 produced from the reaction as follow:

From the balanced equation above,

10 moles of Cl2 reacted to produce 4 moles of PCl5.

Therefore, 0.718 mole of Cl2 will react to produce = (0.718 x 4)/10 = 0.287 mole of PCl5.

Therefore, 0.287 mole of PCl5 is produced from the reaction.
