Answer:

The answer to your question is: D. Fractional distillation

Explanation:

A. Column chromatography this method is use to separate mixtures base in its capacity to be absorbed.

B. Fractional crystallization this method use the solubility of solutes in a solvent.

C. Simple distillation is a method to separate 2 liquids based on the difference in their boiling points.

D. Fractional distillation is a method used to separate a mixture of liquids which have their boiling points very close.

E. Paper chromatography is a method to separate a mixture based on their different rate of migration on a paper.

Fittoniya [83]

Answer:

118.776 mmHg

Explanation:

The equation of the reaction is;

C4H10(g) + 13/2 O2(g) ------> 4CO2(g) + 5H20(g)

Now the mole ratio according to the balanced reaction equation is;

1 : 6.5 : 4 : 5

Hence, the total number of moles present = 1 + 6.5 + 4 + 5 = 16.5 moles

Mole fraction of water vapour = 5/16.5 = 0.303

We also know that;

Partial pressure= mole fraction * total pressure

Partial pressure of H20(g) = 0.303 * 392 mmHg = 118.776 mmHg

Burka [1]

Answer:

The reaction is endothermic

Part A: Yes because there is an immediate reaction of bubbling vigorously.

Part B: It releases energy because when the compounds are added together they are immediately releasing it by bubbling and turning cold.

Part C: Yes because the liquids inside when combined give off coldness that makes the liquid temperature decrease to use this chemical reaction could definitely be used to keep something cold
