- Recall that you are on the board of trustees for a Wisconsin township that frequently experiences winter temperatures of -16 °C. You are responsible for ensuring that the city’s 30,000 residents are able to travel safely in even the coldest and iciest conditions. You must decide if the city purchases the pre-prepared ice melt blend or proposes a new blend for use in winter 2022. You must consider environmental impact, lowest effective temperature, cost, and your experimental results in your decision. Of note, the pre-prepared blend would simplify logistics for the city, but the company’s price includes a $5/ton mixing fee; if you create your own blend, the cost would simply be calculated from the 2022 projected prices of pure compounds in Table 2.1 plus the $5/ton mixing fee. Would you recommend the city purchase the pre-prepared blend or change the percent composition of blended ice melt? Regardless of which choice you recommend, you must include the following in your response:…Report your results including: a) volume collected and % ethanol for each fraction b) % yield of ethanol from molasses c) % yield ethanol from sugars, assuming approximately half of molasses is reactive sugars. Show at least one representative calculation for each part (a, b, and c). The relevant reaction is: C12H22O11 (sucrose) -> 4 CH3CH2OH + 4 CO2. Data: Fraction 1: 1mL ethanol collected, 0.81g Fraction 2L 1mL ethanol collected, 0.95g Fraction 3: 1mL ethanol product collected, 0.97gThe human microbiome is one of the major frontiers of current scientific investigation. Increasing the diversity within your "gut" can be achieved by consuming probiotics from fermented foods and beverages such as sauerkraut and kefir. Kombucha is a tea co-culture of bacteria and yeast (called a SCOBY) and ethanol is one of the products of this fermentation. Lindsey regularly drank kombucha for its perceived health benefits but was concerned about her blood alcohol level. When drinking kombucha, Lindsey's maximum blood alcohol concentration (BAC) reached 0.9 mg/100mL of blood. Given that the initial half-life for ethanol in the body is 40 minutes, what will be Lindsey's BAC after one hour (60 minutes)?
- 3. If both water and your alkene products distill into your collection flask, why might you get two layers? because there is a temperature gradient in the graduated cyclinder because methylcyclohexenes and water are immiscible because methylcyclohexenes and water are miscibleAt 1 atm, a mixture of octane and methylbenzene boils at 135.8 degrees Celsius with a composition of 60% methylbenzene. The boiling points of methylbenzene and octane are 110.6 and 125.6 degrees Celsius, respectively. Draw a boiling point-composition diagram for the octane-methylbenzene mixture system, including all significant labels.Explain why it is problematic to include a constraint such as the following in an LP model for a blending problem: Total octane in gasoline 1 blend $ divided by Barrels of gasoline 1 blended daily which is greater thanor equal to 10
- According to Schwabe and Wagner, the heats of combustion in a constant-volume calorimeter for fumaric and maleic acids are -1337.21 kJ mol-1 and -1360.43 kJ mol-1, respectively, at approximately 25 °C. What is the enthalpy of isomerization of maleic acid into fumaric acid in kJ mol-1?MODIFIED TRUE OR FALSE Write the correct word to make the statement true if it's false 1. The formation of black smoke upon combustion of hydrocarbons indicates incomplete combustion which means that the sample has a [low] C to H ratio. 2. In steam distillation, the desired substance decomposes and is obtained at a temperature [higher] than its actual boiling point.1-A bottle of Na2EDTA.2H2O is labeled with an assay of 100.5%, what is this implied?What is the result of heating to 100 ºC?
- Discuss the trend in predicted vapor pressure of 1. Butane 2. Acetone 3. Acetic Acidplease help me with my assignment. kindly please make it brief and concise ? thank you ^^ need it before 2 pm :( Draw the binary mixture diagram of water and ethanol. Illustrate and explain what will happen if 35 vol% of ethanol (molasses ferment) is fractionally distilled. What would be the composition of the fractionally distilled alcohol?Saturated steam at 232 ° C is used to sterilize a liquid solution. The temperature of the process solution before sterilization is 25 ° C. The temperature of the solution obtained at the end of sterilization 120 ° C. If 1600 kg of saturated steam is used for sterilization, how much sterile solution is obtained at the end of this process? It can be assumed that the liquid solution has the same properties as saturated steam at its respective temperature.
