concentration of the contact solution = 3 %

Explanation:

We have the following data:

10.7 g of hydrogen peroxide H₂O₂

355 g of solution

To calculate the concentration of the contact solution we use the following formula:

concentration = (mass of solute / mass of solution) × 100

concentration of the contact solution = (10.7 / 355) × 100

concentration of the contact solution = 3 %

What is the concentration of a dextrose solution prepared by diluting 16 mL of a 1.0 M dextrose solution to 25 mL using a 25 mL
seraphim [82]

Answer:

0.64 M

Explanation:

Step 1: Given data

  • Initial concentration (C₁): 1.0 M
  • Initial volume (V₁): 16 mL
  • Final concentration (C₂): ?
  • Final volume (V₂): 25 mL

Step 2: Calculate the final concentration of the dextrose solution

We want to prepare a diluted solution from a concentrated one. We can find the final concentration using the dilution rule.

C₁ × V₁ = C₂ × V₂

C₂ = C₁ × V₁ / V₂

C₂ = 1.0 M × 16 mL / 25 mL

C₂ = 0.64 M

Which of the following is consistent with a reaction that proceeds spontaneously in the reverse direction (assume all variables
elena-s [515]

Answer:

B. ΔG > 0, Q > K

Explanation:

For reverse reaction to take place Q should be greater than K

Since reverse reaction should be spontaneous, forward reaction should be non spontaneous.

So, for forward reaction, ΔG > 0

Hence, the correct answer is B

What is the pressure of 0.5 mol of nitrogen gas in a 5 L container at 203 K
Ivan

Answer:

1.67 atm.

Explanation:

  • We can use the general law of ideal gas: PV = nRT.

where, P is the pressure of the gas in atm (P = ??? atm).

V is the volume of the gas in L (V = 5.0 L).

n is the no. of moles of the gas in mol (n = 0.5 mol).

R is the general gas constant (R = 0.0821 L.atm/mol.K),

T is the temperature of the gas in K (T = 203 K).

∴ P = nRT/V = (0.5 mol)(0.0821 L.atm/mol.K)(203 K)/(5.0 L) = 1.67 atm.
