There's 1 drink (and you are asked to determine the glucose concentration in the drink in the units of g/100mL. (Why these units? Well, once you have the concentrations in g/100mL you will be able to compare your values with the nutritional values given on the drink bottles’ labels). The sample of the drink was diluted 1/100 (i.e. by a factor of 100). This was an essential step in the method because, without it, the machine used to analyse the glucose concentration (spectrophotometer) would have given an error as the concentration would have been too high for accurate detection. What this means for you is that the dilution factor will need to be taken into consideration in your calculations (remember the aim is to calculate the concentration in the original drink and not in the diluted drink). You measured the concentration of their diluted drink using the spectrophotometer and their results were provided to them in the units mM (millimolar). Glucose Concentration in mM of drink =…

The concentration of CH3NC was measured at a constant time interval of every 10 seconds over a 5.00 minute period for the isomerization of acetonitrile. CH3CN(g) --> CH3CN(g) The plot of ln[CH3NC] versus time in seconds produced the linear regression equation: y= -6.3x10-3(x) - 1.366 How much time does it take to reach 50% of the initial concentraion for this reaction? a.) 217 s b.) 150 s c.) 20.2 s d.) 110 s

Hello, Can you please answer these 3 questions? Thank you!
V. Error Analysis/Questions For the following questions explain what specific error in calculating your Ksp value would occur (i.e. would the Ksp be too HIGH or too LOW), compared to the situation in which no errors occur. When you answer the question, consider how the situation affects the calculation of Ksp. Each answer must have an explanation and type the answer, please. A. The buret was not conditioned (it still had water in it) when you add the HCl. Would the Ksp be too HIGH or too LOW? B. There was Ca(OH)2 solid (that was not filtered off) in your solution to be titrated. Would the Ksp be too HIGH or too LOW? C. You measured 24.00 mL of Ca(OH)2 solution instead of 25.00 mL. Would the Ksp be too HIGH or too LOW? D. The HCl concentration was actually lower than the reported molarity on the bottle. Would the Ksp be too HIGH or too LOW?
