A student uses 0.001 M potassium thiocyanate solution to make the calibration solutions in the first part of the lab. If the student calculated the concentrations of the thiocyanatoiron(III) complex assuming 0.002 M potassium thiocyanate solution was used, what would the effect be on the student's results? The student carries out the second part of the experiment using solutions with correct concentrations.    The slope of the Beer's Law plot would be less than it should have been, resulting in larger Kc values calculated in the second part.    The slope of the Beer's Law plot would be less than it should have been, resulting in smaller Kc values calculated in the second part of the experiment.      The slope of the Beer's Law plot would be greater than it should have been, resulting in smaller Kc values calculated in the second part of the experiment.      The slope of the Beer's Law plot would be greater than it should have been, resulting in larger Kc values calculated in the second part of the experiment.

Lactase is an enzyme that breaks down the sugar lactose which is commonly found in dairy products. Some people develop lactose intolerance as they grow older and the amount of lactase enzyme in their gut diminishes. Since the enzyme is commonly found in the gut of humans it can withstand a pH that is very acidic, ranging from a pH of 2-7. A student decided to do an experiment to determine how the pH of a solution affects lactase enzyme activity. Lactase works by breaking lactose into its two component sugars of glucose and galactose.   To conduct the experiment the student prepared a solution of lactose and placed it into 5 different test tubes. A pH buffer solution was then added to each test tube with a pH of 2.0 in the first tube, 4.0 in the second, 6.0 in the third, 8.0 in the fourth, and a 10 pH in the fifth. Next, the enzyme lactase was added in equal amounts to each test tube and allowed to sit for ten minutes white the enzyme reacted with the lactose. At the end of the ten…

A solution is prepared such that the initial concentration of A2+ is 1.50x103 M and the initial concentration of X is 4.60x10-3 M. A2+ and X are allowed to react as shown below to establish equilibrium with the complex AX2+. In a colorimetry experiment, the equilibrium concentration of the complex AX2+ is determined to be 8.9x10-4 M. A2* (aq) + X (aq) =Ax2+ (aq) %3D Complete the ICE table below by selecting the correct value or expression to place in the ICE table from the drop-down menu.
