The potential leaving group in the reactant and in the product of the given proton transfer step are to be circled, and the actual form in which it leaves is to be written. The leaving group is to be labeled as a good or a poor leaving group. Concept introduction: A leaving group is the atom or group of atoms that breaks off from the substrate during a substitution or elimination reaction. The leaving group is also a nucleophile and departs with its electron pair from its bond with the carbon atom. A good leaving group must be stable; in solution one, it has departed. This can be determined from its strength as a base. A weak base is a better leaving group than a strong base because it is more stable. This also means that a neutral leaving group is generally more stable than a similar negatively charged leaving group.

1) Suppose 0.1 kg ice at 0°C (273K) is in 0.5kg water at 20°C (293K). What is the change in entropy of the ice as it melts at 0°? To produce the original "water gas" mixture, carbon (in a combustible form known as coke) is reacted with steam: 131.4 kJ + H20(g) + C(s) → CO(g) + H2(g) From this information and the equations in the previous problem, calculate the enthalpy for the combustion or carbon to form carbon dioxide. kindly show me how to solve both parts of the same long problem.

we were assigned to dilute 900ppm in to 18ppm by using only 250ml vol flask. firstly we did calc and convert 900ppm to 0.9 ppm to dilute in 1 liter. to begin the experiment we took 0,225g of kmno4 and dissolved in to 250 vol flask. then further we took 10 ml sample sol and dissolved in to 100 ml vol flask and put it in to a spectrometer and got value of 0.145A . upon further calc we got v2 as 50ml . need to find DF, % error (expval and accptVal), molarity, molality. please write the whole report. thank you The format, tables, introduction, procedure and observation, result, calculations, discussion and conclusion
