“A student in your class claims that chemical bonds and intermolecular forces are the same thing. Is this student correct? Justify your answer”

The answer to your question is below

Explanation:

This student is wrong.

Chemical bonds are forces that hold atoms together to form a molecule or compound. These interactions are inside the molecule. Example

Ionic bond: NaCl   (sodium and chlorine).

Intermolecular forces are weaker than chemical bonds and they are forces between atoms or molecules. These interactions are among different molecules.

Example

Two molecules of water interact forming hydrogen bridges.

i dont know

explanation:

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
