Mole fraction of sodium hypochlorite in 0 .650 m solution has to be calculated. Concept Introduction: Molality is one of the many parameters that is used to express concentration of a solution . It is expressed as, Molality = n u m b e r of m o l e s o f solute m a s s of solvent in kg A solution is at least made up of two components. Mole fraction of a component in the solution correlates to the ratio of number of moles of that component to the total number of moles. It is expressed as, Mole fraction = n u m b e r of moles of a component t o t a l number of moles in the solution

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

Interpretation Introduction

Interpretation:

Mole fraction of sodium hypochlorite in 0.650 m solution has to be calculated.

Concept Introduction:

Molality is one of the many parameters that is used to express concentration of a solution. It is expressed as,

Molality = number of moles of solutemass of solvent in kg

A solution is at least made up of two components. Mole fraction of a component in the solution correlates to the ratio of number of moles of that component to the total number of moles. It is expressed as,

Mole fraction = number of moles of a componenttotal number of moles in the solution

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
