The Ozone Layer's importance comes in its most vital role, providing a means of protection against the Sun's ultraviolet radiation which can normally kill skin cells, and cause cancer to human beings whilst preventing other lifeforms from existing. Ultra violet light also has been shown to bring DNA damage to many types of plants, so the Ozone layer is what allows all this to exist without the constant threat of ultra violet radiation causing significant harm.

I) Predict which of the liquids would cause the largest decrease in mass of a potato stick

rjkz [21]

Answer:

1.0 mole per dm3 sodium chloride solution

Explanation:

<em>The more the molarity of a solution, the lower the water potential of the solution, and the higher the amount of water that will osmotically move from the potato stick to the solution when placed in it in order for an equilibrium to be established. </em>

Hence,<u> the 1.0 mole per dm3 sodium chloride solution will cause the largest decrease in the mass of the potato stick</u> when compared to the 0.5 and 0.1 mole per dm3 sodium chloride solutions.
