68. Step 1: H2SeO3(aq) <=> HSeO3-(aq) + H+(aq) $K_{a1}$ = 2.1 x 10-3 Step 2: HSeO3-(aq) <=> SeO32-(aq) + H+(aq) $K_{a2}$ = 5.3 x 10-9 The step-wise dissociation of selenous acid, H2SeO3(aq), is represented by the equations above. Which of the following best helps explain why the value of $K_{a2}$ is so much smaller than the value of $K_{a1}$? (A) The Se atom in H2SeO3(aq) is in a higher oxidation state than the Se atom in HSeO3(aq). (B) Water is more attracted to HSeO3-(aq) ions than to SeO32- ions, which drives the step 2 equilibrium toward the reactant. (C) The HSeO3-(aq) ions produced in step 1 are asymmetrical, but the SeO32- ions produced in step 2 are symmetrical. (D) Removing the first H+ from H2SeO3(aq) requires less energy than removing the second H+, because the second H+ is removed from a negatively charged species.

Chris and Dakota are on a first date. As they drive, Chris notices the smell of Dakota's shampoo. Throughout the evening, whenever Dakota is close to Chris, Chris not only smells the shampoo but their heart quickens and the palms of their hands become damp. The following week, while walking down the hall at school, Chris smelled Dakota's shampoo. As a result, Chris's heart skipped a beat and they started to sweat. In this example, Dakota's shampoo is a(n) conditioned response conditioned stimulus unconditioned response unconditioned stimulus

1. (15 points) The following is an incomplete Cayley table for a group $ G=\{a, b, c\} $. \begin{tabular}{|l||l|l|l|} \hline$ * $ & $ a $ & $ b $ & $ c $ \\ \hline \hline$ a $ & $ c $ & & \\ \hline$ b $ & & $ b $ & \\ \hline$ c $ & & & $ a $ \\ \hline \end{tabular} So from the table, we know $ a * a=c, b * b=b, c * c=a $. (a) What is the identity? Show your reasoning. (b) Complete the table. (c) What is the inverse for each element $ a, b, c $ (d) Find the orders $ |a|,|b| $ and $ |c| $. (e) Is $ G $ a cyclic group? If yes, list all generators.

Version D A frictionless, disc-shaped merry-go-round with a radius of 4.5 m, and a mass of 175 kg is rotating at 4 rpm. A very large child (70 kg) suddenly sits down right on to the edge. After the child has sat down, what is the angular speed of the merry- go-round and child system? (Hint: the moment of inertia for a disc is the same as that of a solid cylinder)
