Chapter 20: Problem 40

Write equations describing the reactions of Sn with each of the following: \(\mathrm{Cl}_{2}, \mathrm{O}_{2}\), and \(\mathrm{HCl}\).

Short Answer

Expert verified
The balanced chemical equations for the reactions of tin (Sn) with chlorine gas (Cl₂), oxygen gas (O₂), and hydrochloric acid (HCl) are as follows: \( \mathrm{Sn} + 2 \, \mathrm{Cl}_{2} \rightarrow \mathrm{SnCl}_{4} \) \( \mathrm{4 \, Sn} + 2 \, \mathrm{O}_{2} \rightarrow 4 \, \mathrm{SnO}_{2} \) \( \mathrm{Sn} + 2 \, \mathrm{HCl} \rightarrow \mathrm{SnCl}_{2} + \mathrm{H}_{2} \)

Step by step solution

01

Reaction of tin with chlorine gas

The reaction of tin (Sn) with chlorine gas (Cl₂) forms tin(IV) chloride (SnCl₄). To balance the equation, simply combine the elements as shown below: \[\mathrm{Sn} + 2 \, \mathrm{Cl}_{2} \rightarrow \mathrm{SnCl}_{4}\]
02

Reaction of tin with oxygen gas

Tin reacts with oxygen gas (O₂) to form tin(IV) oxide (SnO₂). To balance the equation, we need to adjust the coefficients for the reactants and products, which results in the following balanced equation: \[\mathrm{4 \, Sn} + 2 \, \mathrm{O}_{2} \rightarrow 4 \, \mathrm{SnO}_{2}\]
03

Reaction of tin with hydrochloric acid

Tin reacts with hydrochloric acid (HCl) to form tin(II) chloride (SnCl₂) and hydrogen gas (H₂). To balance the equation, we will adjust the coefficients to ensure the same number of atoms for each element are on both sides: \[\mathrm{Sn} + 2 \, \mathrm{HCl} \rightarrow \mathrm{SnCl}_{2} + \mathrm{H}_{2}\] Now we have successfully written and balanced the chemical equations for the reactions of tin with chlorine gas, oxygen gas, and hydrochloric acid.

What is nitrogen fixation? Give some examples of nitrogen fixation.

. It takes \(15 \mathrm{kWh}\) (kilowatt-hours) of electrical energy to produce \(1.0 \mathrm{~kg}\) of aluminum metal from aluminum oxide by the Hall-Heroult process. Compare this to the amount of energy necessary to melt \(1.0 \mathrm{~kg}\) of aluminum metal. Why is it economically feasible to recycle aluminum cans? (The enthalpy of fusion for aluminum metal is \(10.7 \mathrm{~kJ} / \mathrm{mol}[1\) watt \(=1 \mathrm{~J} / \mathrm{s}] .\) )

The U.S. Public Health Service recommends the fluoridation of water as a means for preventing tooth decay. The recommended concentration is \(1 \mathrm{mg} \mathrm{F}^{-}\) per liter. The presence of calcium ions in hard water can precipitate the added fluoride. What is the maximum molarity of calcium ions in hard water if the fluoride concentration is at the USPHS recommended level? ( \(K_{\text {sp }}\) for \(\left.\mathrm{CaF}_{2}=4.0 \times 10^{-11} .\right)\)

Photogray lenses contain small embedded crystals of solid silver chloride. Silver chloride is light-sensitive because of the reaction $$\mathrm{AgCl}(s) \stackrel{\mathrm{hv}}{\longrightarrow} \mathrm{Ag}(s)+\mathrm{Cl}$$ Small particles of metallic silver cause the lenses to darken. In the lenses this process is reversible. When the light is removed, the reverse reaction occurs. However, when pure white silver chloride is exposed to sunlight it darkens; the reverse reaction does not occur in the dark. a. How do you explain this difference? b. Photogray lenses do become permanently dark in time. How do you account for this?

One pathway for the destruction of ozone in the upper atmosphere is $$\begin{array}{l}\mathrm{O}_{3}(g)+\mathrm{NO}(g) \longrightarrow \mathrm{NO}_{2}(g)+\mathrm{O}_{2}(g) \quad \text { Slow } \\\\\mathrm{NO}_{2}(g)+\mathrm{O}(g) \longrightarrow \mathrm{NO}(g)+\mathrm{O}_{2}(g) \quad \text { Fast } \\ \text { Overall reaction: } \mathrm{O}_{3}(g)+\mathrm{O}(g) \rightarrow 2 \mathrm{O}_{2}(g)\end{array}$$ a. Which species is a catalyst? b. Which species is an intermediate? c. The activation energy \(E_{\mathrm{a}}\) for the uncatalyzed reaction $$\mathrm{O}_{3}(g)+\mathrm{O}(g) \longrightarrow 2 \mathrm{O}_{2}(g)$$ is \(14.0 \mathrm{~kJ} . E_{\mathrm{a}}\) for the same reaction when catalyzed by the presence of \(\mathrm{NO}\) is \(11.9 \mathrm{~kJ} .\) What is the ratio of the rate constant for the catalyzed reaction to that for the uncatalyzed reaction at \(25^{\circ} \mathrm{C}\) ? Assume that the frequency factor \(A\) is the same for each reaction. d. One of the concerns about the use of Freons is that they will migrate to the upper atmosphere, where chlorine atoms can be generated by the reaction $$\mathrm{CCl}_{2} \mathrm{~F}_{2} \stackrel{\mathrm{hr}}{\longrightarrow} \mathrm{CF}_{2} \mathrm{Cl}+\mathrm{Cl}$$ Freon- 12 Chlorine atoms also can act as a catalyst for the destruction of ozone. The first step of a proposed mechanism for chlorinecatalyzed ozone destruction is $$\mathrm{Cl}(g)+\mathrm{O}_{3}(g) \longrightarrow \mathrm{ClO}(g)+\mathrm{O}_{2}(g)$$ Slow Assuming a two-step mechanism, propose the second step in the mechanism and give the overall balanced equation. e. The activation energy for Cl-catalyzed destruction of ozone is \(2.1 \mathrm{~kJ} / \mathrm{mol}\). Estimate the efficiency with which \(\mathrm{Cl}\) atoms destroy ozone as compared with NO molecules at \(25^{\circ} \mathrm{C}\). Assume that the frequency factor \(A\) is the same for each catalyzed reaction and assume similar rate laws for each catalyzed reaction.
