Answer:

20 liters of 50% solution and 80 liters of 25% solution

Explanation:

Let x litres be the amount of 50% solution to be used.

Since the amount of 25% solution used is 20 liters less than 5 times the amount of 50% solution used, then the 25% solution would be (5x -20) litres.

Therefore, 50x + 25(5x-20) = 30(x + 5x-20)

50x + 125x - 500 = 30x + 150x - 6 00

175x - 500 = 180x - 600

Collecting like terms

180x - 175x = 600 - 500

5x = 100

x = 20

Therefore, volume of 50% solution needed = 20 litres

Volume of 25% solution needed = (5 * 20) - 20 = 80 litres

20 liters of 50% solution and 80 liters of 25% solution

Answer:

-114.6°C is the new freezing point

Explanation:

The addition of a solute to a pure solvent produce the decreasing in the freezing point (Freezing point depression, Colligative property). The equation to find the new freezing point of the mixture is:

ΔT = Kf*m*i

Where ΔT is the change in the freezing point,

Kf is the freezing point depression constant of the solvent = 1.99°C/m

m is molality of the solution (Moles of solute / kg solvent)

i is Van't Hoff factor = 1 for nonelectrolytes

Molality of the solution is:

Moles glucose -Molar mass: 180.156g/mol-

10.3g * (1mol / 180.156g) = 0.05717 moles

kg of solvent:

250g * (1kg / 1000g) = 0.250kg

Molality = 0.05717 moles / 0.250kg =

0.2287m

ΔT = 1.99°C/m*0.2287m*1

ΔT = 0.46°C

As the freezing point of ethanol is -114.1°C, the freezing point of te solution is:

-114.1°C - 0.46°C

= -114.6°C is the new freezing point

The value of Kp for the reaction PCl₅(g) ⇌ PCl₃(g) + Cl₂(g) is 4.0.

Initial pressure of PCl₅ (PCl₅(initial)) = 2.5 atm

Pressure of PCl₅ at equilibrium (PCl₅(eq)) = 0.5 atm

Using the equation for Kp:

Kp = (PCl₃ * Cl₂) / PCl₅

We need to find the value of Kp.

Substituting the given pressures:

Kp = (PCl₃(eq) * Cl₂(eq)) / PCl₅(eq)

Kp = (PCl₃(eq) * Cl₂(eq)) / 0.5

Since Kp is a dimensionless constant, we can simplify the equation further.

Kp = (2 * PCl₃(eq) * Cl₂(eq)) / 1

Kp = 2 * PCl₃(eq) * Cl₂(eq)

Now, we need to determine the value of PCl₃(eq) * Cl₂(eq).

To find that, we subtract the initial pressure of PCl₅ from its pressure at equilibrium:

PCl₃(eq) * Cl₂(eq) = PCl₅(initial) - PCl₅(eq)

PCl₃(eq) * Cl₂(eq) = 2.5 - 0.5

PCl₃(eq) * Cl₂(eq) = 2.0

Now, substituting this value back into the equation for Kp:

Kp = 2 * 2.0

Kp = 4.0

The rate of the reaction is 5.45 M/min CO2, and the rate of the concentration change of CO2 is 20 M/min. These values can be obtained using the stoichiometry of the balanced chemical equation.

The balanced chemical equation for the reaction indicates that for every three moles of CH3NH2, 11 moles of HNO3 are consumed, which leads to the formation of three moles of CO2, 13 moles of H2O, and 14 moles of NO. Therefore, the stoichiometry of the reaction is 3:11:3:13:14 for CH3NH2, HNO3, CO2, H2O, and NO, respectively.
Given the rate of disappearance of nitric acid (HNO3) as 20 M/min, we can use the stoichiometry to determine the rate of the reaction and the rate of the concentration change of CO2.
1. Rate of the reaction:
The stoichiometry of the reaction tells us that for every 11 moles of HNO3 consumed, three moles of CO2 are formed. Therefore, the rate of the reaction can be expressed as:
(20 M/min) x (3 mol CO2/11 mol HNO3) = 5.45 M/min CO2
Thus, the rate of the reaction is 5.45 M/min CO2.
2. Rate of the concentration change of CO2:
The stoichiometry of the reaction tells us that for every three moles of CH3NH2 consumed, three moles of CO2 are formed. Therefore, the rate of the concentration change of CO2 can be expressed as:
(20 M/min) x (3 mol CO2/3 mol CH3NH2) = 20 M/min CO2
Thus, the rate of the concentration change of CO2 is 20 M/min.
In conclusion, the rate of the reaction is 5.45 M/min CO2, and the rate of the concentration change of CO2 is 20 M/min. These values can be obtained using the stoichiometry of the balanced chemical equation. It is important to note that the rate of the reaction and the rate of the concentration change of CO2 are different, and they can be determined using different stoichiometric factors.

The statement, that describes potential benefit of using nuclear fusion to produce electricity is "no carbon emission, production of less radioactive waste and energy efficiency."

Nuclear fusion is the process by which two light atomic nuclei merge to produce a single heavier one, releasing huge quantities of energy in the process. Fusion power is a suggested method of generating electricity by utilising heat from nuclear fusion processes.

Fusion reactors, unlike fission reactors, cannot sustain a chain reaction and so can never melt down.

If the correct atoms are used, the fusion reaction creates very little or no radioactive waste. Small amounts of helium, an inert gas that can be safely released without hurting the environment or energy efficiency, are the only byproducts of fusion processes. Less radioactive waste is produced during the fusion process. The fusion reactant is more widely available.
