Shown below is three step mechanism of an alkene reaction. A. Re-draw (copy) the mechanism shown below, and add curved arrows to indicate the electron flow (bond making and bond breaking) for each step of the mechanism. B. For each INTERMOLECULAR STEP in the mechanism, clearly indicate the Lewis acid/base (LA/LB) and whether they are also Bronsted acids/bases (BA/BB). You can just add labels to the mechanism you re-drew for part A. C. For step 1 and 2 of the mechanism, draw the transition states. $H_2O$ $H_2SO_4$ (cat.)

4) Consider the following procedure. A vitamin containing 0.190 + 0.002 g of iron is dissolved in acid. The acid and dissolved vitamin are transferred to a Class A 100 mL volumetric flask and diluted to 100 mL with DI water. From this solution, 1 mL is removed using a Class A, 1 mL volumetric pipet. This 1 mL aliquot is transferred to a second-Class A, 100 mL volumetric flask and diluted to 100 mL using DI water. What is the absolute uncertainty in the solution's concentration? What is the concentration of the iron in the final solution? What measurement uncertainty has the greatest influence on the density's uncertainty? Tolerances for Class A glassware 100 mL volumetric flask 1 mL volumetric pipet +0.08 mL +0.006 mL

Moving to another question will save this response. Question 1 5 points Photons of light carry energy. Two light photons, one with a wavelength of 1.5 micrometers and the other with a wavelength of 3 micrometers, are compared. Which of the following statements is correct? (A) The photon energy is smaller for the 1.5 micrometer light than for the 3.0 micrometer light. (B) The photon energy is equal between the 1.5 micrometer light and the 3.0 micrometer light. (C) The photon energy is larger for the 1.5 micrometer light than for the 3.0 micrometer light. (D) Photon energy cannot be compared between the two lights with different wavelengths.
