The percent atom economy for the following reaction is to be determined. Concept introduction: All the reactant material is not necessarily converted to the desired product. Often, a non favored (side) product is also formed. If the reactant(s) is/are converted completely to the product, the conversion efficiency is 100%. This type of inherent efficiency of the reaction is called percent atom economy, and it is calculated using the equation % Atom economy = Mass of atoms in the desired product Mass of atoms in all reagents × 100 When the numerator and denominator are the same, the atom economy is 100% . On the other hand, when there are by-products that are not useful in the synthesis, the atom economy falls below 100% .

Interpretation Introduction

Interpretation:

The percent atom economy for the following reaction is to be determined.

Concept introduction:

All the reactant material is not necessarily converted to the desired product. Often, a non favored (side) product is also formed. If the reactant(s) is/are converted completely to the product, the conversion efficiency is 100%. This type of inherent efficiency of the reaction is called percent atom economy, and it is calculated using the equation

% Atom economy = Mass of atoms in the desired productMass of atoms in all reagents × 100

When the numerator and denominator are the same, the atom economy is 100%. On the other hand, when there are by-products that are not useful in the synthesis, the atom economy falls below 100%.

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
