Evaporating sweat cools the body because evaporation absorbs 2.44 kJ per gram of water evaported. Estimate the mass of water that must evaporate from the skin to cool a body by 0.50 degrees C, if the mass of the body is 95 kg and its heat capacity is 4.01 J/g degree C. (Remember: convert 2.44 kJ to J and convert 95 kg to g).

I understand the answer is 78 g but I need help with step by step detail. Thank you.

I know it has to do something with Van Der Waals, but I can't seem to find the answer. If you choose to answer the question, I'd really appreciate it if you can back it up with at least some information or facts. Thank you all in advance.

Allright, i know Rutherford won the Nobel prize in 1908 for chemistry because of his research on radioactivity.......but can somebody give me more details like:

What was the exact subject area? and what are the discoveries specific contributions?

Please give me detailed answers.
By the way I've been to the Nobel prize website, the details are more like a biography and are not exactly focused on the prize and the details of the prize.

The following is a half-reaction. I need to know whether oxidation or reduction is involved.

ClO2(g)--->HClO3(ag)

The answer is Oxidized because Cl is changed from +4 to +5. Can someone break this down so i can understand please?
