What is an intramolecular force

1 answer:

4 0

An intramolecular force is any force that binds together the atoms making up a molecule or compound, not to be confused with intermolecular forces, which are the forces present between molecules. The subtle difference in the name comes from the Latin roots of English with inter meaning between or among and intra meaning inside. Chemical bonds are considered to be intramolecular forces, for example. These forces are often stronger than intermolecular forces, which are present between atoms or molecules that are not bonded.

Answer:

$\boxed {\boxed {\sf A. \ 19,320 \ kg/m^3}}$

Explanation:

We want to find the density. The formula is mass over volume.

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

The mass is 500 kilograms. The volume is 0.026 cubic meters.

$m= 500 \ kg \\v=0.026 \ m^3$

Substitute the values into the formula.

$\rho= \frac{ 500 \ kg}{ 0.026 \ m^3}$

Divide.

$\rho = 19230.7692 \ kg/m^3$

This is just about equal to 19,320 kg/m³, so choice A is correct.

What is the temperature of 0.750 mol of a gas stored in a 6,050 mL cylinder al 221 atm?

Rasek [7]

Answer:

T = 246 K

Explanation:

Given that,

Number of moles, n = 0.750 mol

The volume of the cylinder, V = 6850 mL = 6.85 L

Pressure of the gas, P = 2.21 atm

We need to find the temperature of the gas stored in the cylinder. We know that,

PV= nRT

Where

R is gas constant

T is temperature

So,

$T=\dfrac{PV}{nR}\\\\T=\dfrac{2.21\times 6.85}{0.75\times 0.0821}\\T=245.85\ K$

T = 246 K

So, the temperature of the gas is equal to 246 K.

A body of mass 5kg has momentum of 125kgm/s. find the velocity of the body in motion.

borishaifa [10]

Explanation:We have momemtum = mass X velocity

p = mv

OR, p/m = v

v = (125kg m/s)25kg

v = 125/25 m/s

v = 5 m/s
