How much is released by 325g of water as it cools from its boiling point to its freezing point? the specific heat capacity of water is 4.18 j/g° c. report your answer to the nearest kilojoule.

Calculate the expected ph values of the buffer systems from the experiments (a,b,c,d), using the henderson- hasselbalch equation, ph-pka+log[a-]/[ha]. use for pka values carbonic acid= 6.37, and acetic acid= 4.75.
