As a pizza addict....i'd have to say Pepperoni...
Is soluble in water but not soluble in acetonitrile.
So i think its false
As the temperature increases, the solubility of the solute in the liquid also increases. This is due to the fact that the increase in energy allows the liquid to more effectively break up the solute. The additoin of energy also shifts the equilibrium of the reation to the right since it takes energy to dissolve most things and you are adding more of it (this is explained with Le Chatlier principles).
I hope this helps and also I assumed that your question involved the solubility of an ionic substance in a solvent like water. If that was not your question feel free to say so in the comments so that I can answer your actually question.
Emitted/given off. exo is a way to remember that is is going away. think of a flame. the heat is emitted off onto you.
The answer is D) Secrete more hydrogen ions and more bicarbonate ions.
