When compound Y is treated with hot, basic potassium permanganate solution, the only products produced are acetic acid (CH3CO2H) and carbon dioxide. Propose a structure for compound Y.
The chemist used a thermometer that was miscalibrated by 2(degrees)c over the entire thermometer scale. will this factory error cause the reported energy of neutralization to be higher, lower, or unaffected? explain.

A person ate 0.999 pound of cheese (an energy intake of 7990 kJ). Suppose that none of the energy was stored in his body. What mass (in grams) of water would he need to perspire in order to maintain his original temperature? (It takes 44.0 kJ to v..
You have a 134.0g sample of CO2 at -230 oC. You heat it until you have gaseous CO2 at 312 oC. Calculate the total energy required for this process. You will need to find some additional information - heat capacities, phase changes, etc.
