Calculate the aqueous solution with the highest freezing point. These are all solutions of nonvolatile solutes and you should assume ideal Van't Hoff factors where applicable
a) .200 m Ca(ClO4)2
b).200 m K3PO3
c) .200 m HOCH2CH2OH
d) .200 m Ba(NO3)2
e) All of these have the same freezing point
Explain why chemistry is such an important part of the study of Anatomy and Physiology. Please be sure to include specific examples of important chemical reactions as evidence of chemistry's importance to homeostasis.
