The difference in structure between an aldose and a ketose and between an aldopentose and a ketopentose should be determined. Concept introduction: Carbohydrates means hydrate of carbon, they have the general formula C m ( H 2 O ) n (m and n can be same or different). For example: the formula of Glucose is C 6 H 1 2 O 6 , which can alternatively be written as C 6 (H 2 O) 6 . At the molecular level, carbohydrates are polyhydroxy aldehydes and polyhydroxy ketones .

Question

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

Question

Chapter 20, Problem 20.7P

Interpretation Introduction

Interpretation:

The difference in structure between an aldose and a ketose and between an aldopentose and a ketopentose should be determined.

Concept introduction:

Carbohydrates means hydrate of carbon, they have the general formula Cm(H2O)n (m and n can be same or different). For example: the formula of Glucose is C₆ H₁₂ O₆, which can alternatively be written as C₆ (H₂ O)₆.

At the molecular level, carbohydrates are polyhydroxy aldehydes and polyhydroxy ketones.

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
