Question 7 On your paper,  copy each reaction and place the missing information to complete the chemical reaction. (4 pts each, 16 pts total). Aside from the reagent, EACH ANSWER MUST BE DRAWN IN LINE ANGLE (not condensed). If you are naming structures, it will be suspected you are using AI and unauthorized resources.

(5 possible extra credit points) DO NOT COPY THE QUESTION, ONLY GIVE THE ANSWER. This reaction can be achieved using ___________ temperature. A. High B. Low C. It doesn’t matter D. It’s an impossible product. For 3 extra points, in the realm of reactions with conjugated dienes, this product is called the ____________________________ product. (the number of underscores does not indicate the number of letters)

Question 9 (18 pts.)  For the following reaction, DRAW a full curved-arrow pushing mechanism for formation of the products and indicate the Lewis acid and base at each step (LA or LB) and whether they are also Bronsted acids and bases (BA or BB). Each step should have organic structures that are drawn in FULL LINE ANGLE STRUCTURES.     

A bicycle tire has a radius of 0.350 m. The bicycle travels at a constant speed of 14.0 m/s for 40.0 s. What angular distance does the tire rotate through?

A mechanic pushes perpendicular to the end of a 0.40 m long wrench, producing a torque of 72 N·m. What force does the mechanic apply?

Exam 3 – Q12.pngA uniform wooden shelf has a mass of 3.00 kg and a length of 1.20 m. It is supported by a fulcrum located 0.40 m from its left end. A 25.0-N flower pot is placed 0.15 m from the left end. A second object weighing 40.0 N is placed at a distance x from the left end so that the shelf is in equilibrium. a. Draw a free-body diagram of the shelf. b. Calculate the torque due to the 25.0 N object. c. Calculate the weight of the shelf and the torque due to its weight. d. Calculate the location x of the 40.0 N object. e. Determine the upward force exerted by the support.

A 0.200 kg grinding wheel rotates about its center with an angular speed of 12 rad/s. The wheel has an angular momentum of 5.76 kg·m²/s. Assume the wheel is a solid disk (I=12mr2)\left(I=\frac12mr^2\right). What is the radius of the wheel?
