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

Chapter 11, Problem 4RQ

Interpretation Introduction

Interpretation: The factors such as structure, pressure and temperature on solubility has to be discussed. Henry law and the reason why Henry law does not work for Hydrochloric acid has to be explained. The terms hydrophobic and hydrophilic has to be explained.

Concept Introduction:

Henry’s law can be given as the quantity of gas dissolve in a solution is proportional to the pressure of the gas above the solution.

Henry’s law gives the relationship between the pressure of the gas and the concentration of gas dissolved. The equation can be given as,

C=kP

where, C= Concentration of the gas dissolved

k=constant

P=Partial pressure of the solute in gaseous solute

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
