Achemist has been given a mixture of two liquids that form a solution. the liquids have different boiling points, densities, and colors. which method should be used to most easily separate the two liquids? a - distillation b - filtration c - sedimentation d - evaporation

A. Distillation. If the mixtures have different boiling points, the liquid with the lower boiling point will distill off first, followed by the other one.

“B. Filtration” is incorrect. Both liquids will pass through the filter paper.

“C. Sedimentation” is incorrect because it works only for a solid suspended in a liquid.

“D. Evaporation” is incorrect. Both liquids will pass into the atmosphere never to be seen again.

b) mutualism

hope this : )

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 :
