ify the variables being controlled and the variables being changed between the two solutions. Which identification of the variables is correct?
Options:

The volume of the solution and the concentration of the solution are being changed between the two solutions, but the number of solute particles is being held constant.


The number of solute particles and the concentration of the solution are being changed between the two solutions, but the volume is being held constant.


The number of solute particles is being changed between the two solutions, but the volume and concentration of the solution is being held constant.

What would happen to the oxygen atoms in ozone if the ozone layer were completely destroyed by ultraviolet radiation?
ale4655 [162]

When the oxygen atoms in ozone layer were destroyed by ultraviolet radiations the individual oxygen atoms will make bond with each other and form paired oxygen molecules again to form ozone.

What is the ozone layer?

Ozone layer has a high concentration of ozone (O3) in comparison to the rest of the atmosphere, although it is still low in comparison to other gases in the stratosphere.

The ozone layer contains less than ten parts per million of ozone, whereas the normal ozone concentration in the Earth's atmosphere is around 0.3 parts per million. The ozone layer is mostly found in the lower stratosphere.
