Before slow cooking a meat (for example, in a crockpot/slow-cooker) you will often find instructions to sear the meat on high heat in an oiled skillet for a few minutes before transferring it to the crockpot. The searing is brief – not long enough to cook the meat thoroughly. Despite myth/legend, the searing will not “seal in the juices”. What is the searing for?

Course name: College Chemistry. Lab The answer must be handwritten and step by step a clear explanation. Course code: 141 1. When yeast is added to a solution of glucose or fructose, the sugars are said to undergo fermentation and ethyl alcohol is produced. C6H1206(aq) →→→→C₂H5OH(aq) + CO₂(g) This is the reaction by which wines are produced from grape juice. Calculate the mole of ethyl alcohol produced when 1.75 mol glucose molecules undergo this reaction. (2 marks)
Use the following information to answer numerical-response question 10. Crude oil is separated into different groups of hydrocarbons, or fractions, in a fractional distillation tower. Two different locations at which fractions can be removed from the tower are labelled in the diagram below. Numerical Response Fractional Distillation Tower Crude oil K-11090 the greatest amount of CH4(g) is numbered the largest molecules is numbered molecules with the highest boiling points is numbered 10. Match the numbers of the locations in the diagram above with the descriptions of the fractions that could be removed as given below.
