What can contamination of reagents leads to? Unreliable results Reliable results Reproducible results Good results Catalase is the enzyme found in potatoes and It decomposes hydrogen peroxide (H202) to form water and oxygen gas. H202 + catalase - ----> H2O + 02 +E. The reaction is maintained at temperature 40 degree Celsius and there was a formation of bubbles. Based on the enzymatic reaction given, What do you think is the substance responsible for the formation of bubbles? Oxygen gas Hydrogen gas no reaction, because the enzyme catalase will be deactivated no reaction, because the enzyme catalase will be denatured Other: Based on the Fehling's test video, do you think the sugars ribose (in RNA) and the deoxyribose (in DNA) will both form a positive result (red precipitate) No Yes

The ampicillin monograph states that the reconstituted suspension is stable for 14 days in a refrigerator (50C). If the product is left at room temperature (250C) for 6 hours, what is the reduction in the expiration period? (Assume Q10 = 3) Ans is 11.75 days please help Do not give handwriting solution.

1-Bromobutane reacts with water to form 1-butanol according to the following equation. C4H,Br(aq) + 2 H20(1) → C¿H,OH(aq) + H30*(aq) + Br¯(aq) The following is a proposed mechanism for the reaction. C4H9B1(aq) → C4H,*(aq) + Br¯(aq) C4H,*(aq) + H,0(1) → C4H3OH,*(aq) C,H,OH,*(aq) + H,0() – CH,OH(aq) + H30*(aq) slow fast fast Determine the overall rate law for this proposed mechanism. (Rate expressions take the general form: rate = k. [A]ª . [B]°.) chemPad Help Greek - Rate=k[C4H9B1][H2o²] Rate=k[C_4H_9Br][H_2O^2] Remember that answers are case-sensitive.

A research group discovers a neW version oI happyasee, which they nappyase", that catalyzes the chemical reaction HAPPY = SAD The researchers begin to characterize the enzyme. In the first experiment, with [E] at 4 nM, they find that the Vmax is 1.6 µM s-1. Based on this experiment, what is the kcat for happyase*? kcat 400 S In another experiment, with [E,] at 1 nM and [HAPPY] at 30 µM, the researchers find that Vo is equal to 300 nM s-1. What i the measured Km of happyase* for its substrate HAPPY? Km 10 x10–6 Incorrect Further research shows that the purified happyase* used in the first two experiments was actually contaminated with a reversible inhibitor called ANGER. When ANGER is carefully removed from the happyase* preparation, and the two experiments repeated, the measured Vmax increases to 4.8 µM s-, and the measured Km is now 15 µM. S For the inhibitor ANGER, calculate the values of a' and a. a' 2 Incorrect 2

The acid-catalyzed hydrolysis of sucrose, C12H22O11 + H₂O + H+ -> C6H12O6 + C6H12O6 + H+ is known as "inversion of sucrose" because the angle, a, by which the solution rotates polarized light changes from positive to negative as the reaction proceeds (data from 30 degree C): t/hr a 0 78 2 71 4 12 18 24 42 65.10 44.60 32.40 22.45 2.30 48 -1.96 61 -9 86 95 -15.80 -17.25 -21.15 ∞ Use this data to show that the reaction is first order and determine its rate coefficient (at 30 degree C).
