Question 10 a chemistry student adds a quantity of an unknown solid compound x to 150. ml of distilled water at 26.° c. after 10 minutes of stirring, all of the x has dissolved. the student then drains off the solution and evaporates the water under vacuum. a precipitate is left behind. the student washes, dries and weighs the precipitate. it weighs 3.45 g .

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.

explanation:

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
