<u>Answer:</u> The percent yield of the compound is 30.86 %.
<u>Explanation:</u>
To calculate the percentage yield of a compound, we use the equation:

Experimental yield of compound = 25 g
Theoretical yield of compound = 81 g
Putting values in above equation, we get:

Hence, the percent yield of the compound is 30.86 %.
Explanation:
It should be decreasing, and the potential energy increasing, since Law of Conversation of Energy, right?
Also, if you think about what happens when it goes down, it loses potential and gains kinetic, so maybe the opposite should happen when it goes up.
Plants can produce asexually as well as protest so I would reject animals out of the choices. Now to determine the right answer we would have to decide which organisms MOST produce asexually and I would go with Plants

Dissolving involves two materials; the resulting solution is a mixture of both. The dissolved substance is still present in the solution even though it can't be seen.</span>
