Use the solubility table for kbr below to determine the following:
solubility (g kbr / 100 g
h20)
65
80
90
100
110
temp (c)
20
40
60
80
100
is the dissolution of kbr an exothermic or endothermic process ?

As temperature goes up, solubility goes up. That means it's an endothermic reaction, because it takes in heat, and when there's more heat to take in, it reacts more.

explanation:

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
