Answer:

53.4 % is the percent yield

Explanation:

This is the reaction:

C₆H₆ + Cl₂ → C₆H₅Cl + HCl

First of all we need to know the moles of benzene we used

39 g . 1 mol / 78 g = 0.5 moles

Ratio is 1:1 so 1 mol of benzene produces 1 mol of chloride

0.5 moles of chloride were produced by 0.5 moles of benzene

We must calculate the mass of chloride we produced

0.5 mol . 112.45 g / 1 mol = 56.2g

Let's calculate the  percent yield

(Yield produced / Theoretical yield ) . 100

(30 g / 56.2 g) . 100 = 53.4 %

OxYgen and hydrogen particles are kept in a container. Which of the following
Tema [17]

Answer:

Option D

Oxygen particles mix evenly with hydrogen particles.

Explanation:

Diffusion refers to the movement of gasses from a region of higher concentration to a region of lower concentration.

Diffusion occurs in gases because their particles are in a state of constant random motion.

Due to this continuous random motion, once the oxygen and the hydrogen are added to the container, they will begin to mix freely with each other until they fill up the entire volume of the container.

Which gas diffuses most rapidly when they are all at the same temperature and pressure? He, O2, NH3, H2S, or They all diffuse at
Sonbull [250]

Answer:

He

Explanation:

From Graham's law of diffusion, lighter or less dense gas tends to diffuse faster than denser gas amongst the list, He is the lightest gas and so will diffuse faster
