Hard liquors or spirits, such as brandy, whisky, and tequila, are commonly produced by fermentation of carbohydrate-rich natural products. In the process, a mixture containing water (C), ethanol (B), methanol (A), and many other components is generated. Methanol needs to be removed because of its toxic properties; water is extracted to produce beverages with various concentrations of ethanol. a. What differentiating characteristic could be used to separate methanol, ethanol, and water? What experimental technique could be used to separate these substances?
b. As you heat up the alcoholic mixture, in which order will the three substances (A-Methanol, B-Ethanol, C-Water) separate?
c. At which temperatures will each fraction distill?
d. Is there any advantage in changing the pressure at which the distillation is performed? Why?

There are two containers: one container with a 0.15 molar solution of compound A and another with 0.20 molar solution of compound B. What is true about these two containers? O Container A has more moles than B. Container B has more moles than A. They contain an equal number of moles. Not enough information is given.

Answers

Answer:

Container having 0.20 moles of compound has more moles than the container with 0.15 moles of compound A.

Explanation:

Molarity is defined as ratio of  moles of compound to the volume of solution in liters.

Molarity of compound A solution= 0.15 molar = 0.15 mol/L

This means that 0.15 moles of compound A are present in 1 L of solution.

Molarity of compound B solution= 0.20 molar = 0.20 mol/L

This means that 0.20 moles of compound B are present in 1 L of solution.

As we can see that , 0.15 mol < 0.20 mol which indicates that container with compound B has more mole the the container with compound A moles.

What is the pressure in atm exerted by 2.48 moles of a gas in a 250.0 mL container at 58 degrees celsius

Answers

Since the question manages to include moles, pressure, volume, and temperature, then it is evident that in order to find the answer we will have to use the Ideal Gas Equation:  PV = nRT (where P = pressure; V = volume; n = number of moles; R = the Universal Constant [0.082 L·atm/mol·K]; and temperature.

First, in order to work out the questions, there is a need to convert the volume to Litres and the temperature to Kelvin based on the equation:
         250 mL = 0.250 L
             58 °C = 331 K

Also, based on the equation   P = nRT ÷ V

⇒         P  = (2.48 mol)(0.082 L · atm/mol · K)(331 K)  ÷  0.250 L
⇒         P  =  (67.31  L · atm) ÷ 0.250 L
⇒         P  =  269.25 atm

Thus the pressure exerted by the gas in the container is  269.25 atm.

Why did Rutherford conclude that the atom was mostly empty space?

Answers

Rutherford came to this conclusion after his Gold-Foil experiment. He found that most of the alpha particales(when released) went straight through the gold foil, of which consisted of atoms. In the middle of the atom theres a small nucleus that has mass and positive charge. Because the nucleus is so small the alpha particles were able to go straight through leading to the conclusion that atoms are mostly empty space.

Consider the reaction N2O4(g)→2NO2(g) where N2O4 is colorless and NO2 is brown. At a temperature of 5∘C, the reaction is colorless at equilibrium. This indicates that the equilibrium constant for this reaction at this temperature is View Available Hint(s) Consider the reaction where is colorless and is brown. At a temperature of 5, the reaction is colorless at equilibrium. This indicates that the equilibrium constant for this reaction at this temperature is zero, because equilibrium can only be obtained at A. room temperature. B. large. C. negative. D. small (< 1).

Answers

Hey there!:

Answer is small (less than 1).

Keq =  [NO2]² / [N2O4]

At equilibrium  concentration of NO2 is very less and concentration of N2O4 will be more. hence equilibrium constant will be less than one

Hope this helps!
