<u>Answer: </u>The correct answer is option D.

<u>Explanation:</u>

The number of collisions that take place per second per unit volume of the reaction is called as collision frequency.

Particles undergoing only effective collision will lead to chemical reactions.

For a collision to be effective, the colliding molecules must have energy more than a particular value known as threshold frequency.

The factors which are responsible for the number of effective collisions are:

  • Energy factor which means that the colliding molecules must have energy greater than the threshold energy.
  • Orientation factor which means that the colliding molecules must have proper orientations at the time of collisions.

Hence, the correct answer is option D.

When 20.0 grams of an unknown compound are dissolved in 500. grams of benzene, the freezing point of the resulting solution is 3
Lelu [443]

Answer: 120g/mol

Explanation:

The first step we are to take is to calculate the freezing point depression of the solution.

ΔT(f) = freezing point of pure solvent - freezing point of solution

ΔT(f) = 5.48 - 3.77

ΔT(f) = 1.71°C

Next we are to calculate the molal concentration of the solution using freezing point depression

ΔT(f) = K(f) * m

m = ΔT(f)/K(f)

m = 1.71/5.12

m = 0.333 molal

Now, we calculate the molecular weight of the unknown...

m = 0.333 mol = 0.333 mol X per kg of benzene

moles of X = 0.333 mol of X per kg of benzene * 0.5kg of benzene

moles of X = 0.1665

molecular weight of X = 20g of X/0.1665

molecular weight of X = 120/mol

Chris noticed a high-pressure system in the weather forecast for Monday
Alchen [17]

Answer:

A. Clear and Sunny

Explanation:

The answer would be A. Clear and Sunny. A high pressure system occurs where the air mass above the Earth is denser than in surrounding areas, and therefore exerts a higher force or pressure. They usually happen with li9ght winds. Using process of elimination, it could not be D. Warm and Stormy, C. Cloudy and Rainy, or B. Cold and Stormy because all have wet climates.
