The greenhouse effect<span> is the process by the temperature of surface of earth increases because of earth's atmosphere. 

Mechanism:
</span>

Sun emits a broad band of visible light spanning from red to blue colour. In addition to this, it emits UV and IR radiation. Infrared radiations have wavelength longer than IR, while UV ray have wavelength shorter than visible light. Each of these radiations are received on the earth's surface. On receiving radiation, part of it is absorbed by earth and remaining is reflected back. Generally, light of longer wavelength (IR) is reflected to larger extend as compared to shorter wavelength.  Due to this, air present in atmosphere gets heated up. It must be noted that,  molecule like CO2, which is present in air absorbs light from both direct and reflected  fraction of light. This phenomenon is referred as  green house effect. Molecule which absorb long wavelength light (IR) are present in atmosphere due to human activities. Hence, green house effect is often considered to arise because of human activities of altering the composition of air.

The image shows particles of salt dissolved in water.
user100 [1]

Answer: Hope it may help you

Explanation:

Diffusion can be defined as the movement of particles from a region where there a more concentration of solute to the region having less concentration of the solute.

Here, the salt particles will move from right side of the box to the left side of the box.

This is because the right side has more particle and the left side has less particles so they will move towards the left side.

You have to make 500 mL of a 1.50 M BaCl2. You have 2.0 M barium chloride solution available. Determine how to make the needed d
Inga [223]

Answer:

You need 375 mL of BaCl2 solution.

Explanation:

M1V1=M2V2

Dilution formula. Substitute known values and solve for V1.

M1 = 2.0 M

M2 = 1.50 M

V2 = 500 mL

(2.0 M)(V1) = (1.50 M)(500 mL)

V1 = (1.50 M)(500 mL) / (2.0 M)

V1 = 375 mL

The individual components of a solution_____.
Misha Larkins [42]
Its been awhile since I've dabbled in chemistry, but i do know that A isnt the answer because the question says solution, not mixture. This looks somewhat like a trick question, it says individual components, so the answer would be C. This is because the individual components do react to form a compound. B and D would be true if it didnt say individual components, so the question is basically focusing on only one ingredient, not the whole solution. Answer: C

Which of the following has potential energy but no kinetic energy? Longitudinal sound waves An arrow shot from a bow A compresse
Vikentia [17]

Answer:

A compressed spring

Explanation:

A compressed spring has potential energy only and no kinetic energy.

This is because kinetic energy is only possessed by particles in motion.

Energy in a compressed spring= -1/2kx² where x is the displacement.

In this equation there is no velocity so there is no kinetic energy.
