In the formation of acid rain, sulfur dioxide $(SO_2)$ reacts with oxygen and water in the air to form sulfuric acid $(H_2SO_4)$. Write the balanced chemical equation for the reaction. If 2.50 g of $SO_2$ reacts with excess oxygen and water, how much $H_2SO_4$, in grams, is produced?

(II) Suppose the top surface of the vessel in Fig. 13-58 is subjected to an external pressure $P_2$ in addition to atmospheric pressure $P_0$. If $P_2=0.85 \mathrm{~atm}$ and $y_2-y_1=2.4 \mathrm{~m}$, determine $v_1$ for water.

Cite two pieces of evidence to support the statement that water molecules in the liquid state exert considerable attractive force on one another.

The rate of a reaction was followed by measuring the absorption of light by the reactants and products as a function of wavelength $\left(\lambda_1, \lambda_2, \lambda_3\right)$ as time progressed (see Figure on p. 771). Which of the following mechanisms is consistent with the experimental data? (a) $\mathrm{A} \longrightarrow \mathrm{B}, \mathrm{A} \longrightarrow \mathrm{C}$. (b) $\mathrm{A} \longrightarrow \mathrm{B}+\mathrm{C}$. (c) $\mathrm{A} \longrightarrow \mathrm{B}, \mathrm{B} \longrightarrow \mathrm{C}+\mathrm{D}$. (d) $\mathrm{A} \longrightarrow \mathrm{B}, \mathrm{B} \longrightarrow \mathrm{C}$.

A balanced chemical equation contains the term "3 Ca $\left(\mathrm{PO}_4\right)_2$-" How many atoms of each element does this represent in the molecular view? How many moles of each element does this represent on the laboratory scale?

A capacitor with a value of 10 mF has a leakage resistance of 2 $\mathrm{M} \Omega$. How long does it take the voltage across the capacitor to decay to 40% of the initial voltage to which the capacitor is charged? Assume that the capacitor is charged and then set aside by itself.

A 4.00-mF capacitor is connected in series with a 7.00-mH inductor. The peak current in the wires between the capacitor and the inductor is $3.00 \mathrm{~A}$. b) Write an expression for the charge on the capacitor as a function of time, assuming the capacitor is fully charged at $t=0 \mathrm{~s}$.
