Which of the following would be the best technique to use in order to separate a liquid from a solution? (2 points) chromatography evaporation filtration simple distillation

Option (d) is the correct answer.

Explanation:

Simple distillation is defined as a process in which a solution of two liquids with different boiling points is heated. The liquid with low boiling point evaporates readily and it vapors are collected through evaporation.

Hence, both the liquids are separated from each other.

Whereas chromatogarphy is a technique of separating components of a mixture into its substances.

Evaporation is a process in which liquid phase of a substance changes into vapor or gaseous phase.

Filtration is a technique of separating solid components in a solution with the help of a filtering medium.

Hence, we can conclude that best technique to use in order to separate a liquid from a solution is simple distillation.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

what is the average time it took the car to travel 0.25 meters?

⇒ 2.23 seconds

what is the average time it took the car to travel 0.50 meters?

⇒ 3.13 seconds
