Answer: Option (b) is the correct answer.

Explanation:

In liquids, the molecules are held by strong intermolecular forces of attraction as compared to gases. Due to which they are able to collide and slide past each other. Hence, they have a medium kinetic energy.

And, in liquid molecules there is moderate intermolecular distance between the particles.

In gases, the molecules are held by weak Vander waal forces. Hence, they have high kinetic energy due to which they move very rapidly from one place to another leading to more number of collisions.

Hence, gases are able to expand more rapidly as compared to liquids. Therefore, between the atoms of a gas there are large intermolecular distances.

Therefore, we can conclude that the statement particles collide in gas so Substance X is a gas, best describes the two substances.

A liquid that occupies a volume of 0.820 L has a mass of 2.56 kg.

user100 [1]

Answer:

The density of this liquid is 0.320 kg/L

Explanation:

Given:

Volume of the Liquid = 0.820 L

Mass of the liquid = 2.56 kg.

To Find:

The density of the liquid in kg/L

Solution:

Density is the mass occupied by the substance in unit volume. This density is essential determining whether the substance floats or sinks. Greek letter(rho) is used to denote density

The equation of for density is

$Density = \frac{mass}{volume}$

$\rho = \frac{m}{v}$

where m is the mass

v is the volume

On substituting the given values

$\rho = \frac{0.820 }{2.56}$

$\rho = 0.320 kg/L$

What effect does an increase in products have on the reaction rate of a mixture at equilibrium? A. The forward reaction rate inc

Anna007 [38]

Answer:

D. The reverse reaction rate increases.

Explanation:

The rate of reverse increases if the products are increased in a mixture at equilibrium.

At first, rate of forward and backward reactions are same for a mixture in equilibrium. 

If we add products or,the reaction moves to the opposite side I.e towards reactants side.

so,according to the Le Chateliers principle,the reaction shifts opposite to the side of increase. so,according to the Le Chateliers priciple, the rate of reverse or backward reaction will increase with the increase in the products.
