Faster molecules have fewer collisions than slower molecules is True about molecular speed.

<h3>What is Molecular speed?</h3>

Molecular speed refers to the average distance gases or molecules travelled atca particular time rate.

It is valid in ideal gas, where the molecules do not interact with others.

Average molecular speed = Square root (3 (ideal gas constant) * (Temperature)/m)

Therefore, Faster molecules have fewer collisions than slower molecules is True about molecular speed.

A brick has a mass of 100 G and a volume of 25CM3 what is the density of the brick

kumpel [21]

Answer:

$\boxed {\boxed {\sf 4 \ g/cm^3}}$

Explanation:

We are asked to find the density of a brick. Density is a substance's mass per unit volume. The formula for calculating density is as follows.

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

The mass of the brick is 100 grams and the volume is 25 cubic centimeters.

m= 100 g
v= 25 cm³

Substitute the values into the formula.

$\rho= \frac{ 100 \ g}{25 \ cm^3}$

Divide.

$\rho=4 \ g/cm^3$

The density of the brick is <u>4 grams per cubic centimeter.</u>

Ganezh [65]

Answer:

Check the explanation

Explanation:

When there are two molecules then these molecules are described as stereoisomers if they are comprised of the same atoms associated in the same sequence, but the atoms are situated differently in the space. The disparity between stereoisomers can only be observed when the molecules is considered in a three-dimensional arrangement.
