Interpretation Introduction

(a)

Interpretation:

In the given figure every region of constructive interference and destructive interference between the HOMO and LUMO is to be labeled.

Concept introduction:

The HOMO-LUMO orbital interaction concept is used to know how the reacting species interact. The electron-rich species is HOMO while the electron-deficient species is LUMO; they determine substantial net overlap in the transition state. When these two orbitals overlap with the same phases, the constructive interference occurs and the reaction is likely to be allowed. When these two orbitals overlap with the opposite phases, the destructive interference occurs and the reaction is likely to be not allowed (or forbidden).

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. Thanks
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
Q5. Predict the organic product(s) for the following transformations. If no reaction will take place (or the reaction is not synthetically useful), write "N.R.". Determine what type of transition state is present for each reaction (think Hammond Postulate). I Br₂ CH3 F2, light CH3 Heat CH3 F₂ Heat Br2, light 12, light CH3 Cl2, light No
