Zinc metal reacts with hydrochloric acid according to the following balanced equation: Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g) When 0.121 g of Zn(s) is combined with enough HCl to make 50.6 mL of solution in a coffee-cup calorimeter, all of the zinc reacts, raising the temperature of the solution from 21.8 ∘C to 24.5 ∘C. Find ΔHrxn for this reaction as written. (Use 1.00 g/mL for the density of the solution and 4.18 J/(g⋅∘C) as the specific heat capacity.)

32. On January 1, 2024, Macabantog Company insured the life of its president for P5,000,000 with an annual premium of P150,000 payable in advance at the beginning of each year. The company is the designated beneficiary and has the right to cancel the policy at its own option. The cash surrender value of the policy at the end of each policy year are as follows: \begin{tabular}{|cc|} \hline & Cash surrender value \\ 2024 & $ \mathrm{P0} $ \\ 2025 & PO \\ 2026 & $ \mathrm{P} 48,000 $ \\ 2027 & $ \mathrm{P} 64,000 $ \\ 2028 & $ \mathrm{P} 75,000 $ \\ \hline \end{tabular} The president of Macabantog died on September 30, 2028.

Capacitors $C_1 = 34.2 \, \mu F$, $C_2 = 88.8 \, \mu F$ and $C_3 = 185.6 \, \mu F$ were uncharged before being connected to the battery $V = 58.05 \, V$ as shown in the figure below. How much work $W$ was done by the battery to charge those capacitors to their current state in the shown circuit?: $W = \text{____} \, mJ$. How much energy $U_1$ is now stored in capacitor $C_1$?: $U_1 = \text{____} \, mJ$. How much energy $U_2$ is now stored in capacitor $C_2$?: $U_2 = \text{____} \, mJ$. How much energy $U_3$ is now stored in capacitor $C_3$?: $U_3 = \text{____} \, mJ$. Based on your numerical calculations above, what exact fraction of the work done by the battery would be stored in all capacitors?: $\frac{U_1 + U_2 + U_3}{W} = \text{____}$.

Randolph considers PCs and the Windows operating system to be perfect complements. When Randolph maximizes his utility, what will his optimal bundle of PCs and the Windows operating system probably look like? Randolph's indifference curves will be L-shaped. His optimal bundle will lude both goods, consumed in a fixed proportion to one another. Randolph's indifference curves will be convex to the origin. His optimal bundle will likely include both products, with the relative proportions partially determined by their relative prices. Randolph's indifference curves will be concave to the origin. His optimal bundle will likely consist of just 1 one product. Randolph's indifference curves will be straight lines. His optimal bundle will likely consist of just 1 good.
