I) predict which of the liquids would cause the largest decrease in mass of potato stick
oksian1 [2.3K]

Answer:

1 mol per dm3 sodium chloride solution

Explanation:

The liquid that would cause the largest decrease in the mass of the potato stick would be the one with  <u>1 mole per dm3 sodium chloride solution.</u>

<em>The water potential of a solution depends on the molarity of the solution, the higher the molarity, the lower the water potential and vice versa. Hence, a solution with higher molarity has the tendency to osmotically draw more water from the potato stick than a solution with lower molarity.</em>

Therefore, the potato stick will have the largest decrease in mass in 1 mol per dm3 sodium chloride when compared to the 0.5 and 0.1 mole per dm3 solutions.

A partial dislocation or misalignment of a joint is known as what?
lesya [120]
A partial dislocation or misalignment of a joint is known as subluxation

This is when a joint slides out of position but can slide back in on its own. This is different to a luxation (or full dislocation) where the joint completely comes out and has to be put back in with human assistance.

I hope this helps! I'm happy to answer any other questions you might have :)
