The table below shows the main components of Earth's atmosphere. What is the solvent in air? What are the solutes?

The correct answer is - nitrogen is solvent and other gases present in the air are solutes.

Explanation:

As it is given and we know that the earth's atmosphere is made up of various gases including nitrogen, oxygen, carbon dioxide, argon, and water vapor, however, the major part of the atmosphere is made up of nitrogen.

Air is a homogenous mixture of gases and most of the part of the air is, 78.08 percent, nitrogen makes it solvent and other gases mixed with nitrogen are solutes including carbon dioxide and oxygen.

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
