Which of the followings cannot be used to separate table sugar and from sugar-water mixture? O...
Which technique (simple, fractional, or steam distillation) should be used to separate a hexane-water mixture.
Which distillation setup would you use to separate a mixture of toluene (boiling point = 110.6 C) and hexane (boiling point = 68 C)? Explain your choice. Which distillation setup would you use to separate a mixture of benzene (boiling point = 80.1 C) and pentane (boiling point = 36.1 C) Explain your choice.
In our lab, we will be preparing ethanol from the fermentation of sugar with the help of enzymes present in yeast. "An ethanol concentration of 12% or higher is toxic to yeast; therefore distillation is required to produce ethanol in higher concentrations, In this experiment, ethanol will be produced from sucrose (table sugar) and yeast, and the restulting fermentate will be distilled to produce an ethanol-water mixture that is typically at least 90% ethanol. Note that 100% ethanol cannot be...
Question 19 1 pts Which technique would be best suited to separate a mixture of compounds that differ primarily by their boiling point, 110 °C versus 145 °C? infrared spectroscopy distillation O thin layer chromatography O reflux O liquid-liquid extraction
It is desired to separate benzene from a water-benzene mixture in a distillation column operating at a constant pressure of 1 atm (760 mmHg). - Determine the temperature range of the column operation. - Draw the phase diagram of the mixture (versus x and y). - Draw the y-x equilibrium curve of the most volatile component and the 45-degree line in the same figure.

A 11.56 g mixture of sugar (C_12H_22O_M) and table salt (NaCl) is dissolved in 203 g of water. The freezing point of the solution was measured as -2 57 degree C Calculate the mass percent of sugar in the mixture. A list of K_t values can be found here.
A 14.23 g mixture of sugar (C_12H_22O_11) and table salt (NaCI) is dissolved in 177 g of water. The freezing point of the solution was measured as -3.41 degree C. Calculate the mass percent of sugar in the mixture. A list of K_f values can be found here Number %
2. If a person cannot drink salt water, why can they drink sugar water? 3. Carrots were weighed, soaked in 4 different salt solutions and then re-weighed. Horace collected the weight changes (g) carefully: +2, -4,-1,0 Unfortunately, he forgot which weight change matched which salt solution. Predict which numbers should go where on the table below. Salt (g) added to 300 ml Weight change (g) water 10 20 5. In the table above, when the weight change is "O", the...
