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:

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.

it means there are 3 atoms of oxygen
