Chapter 13, Problem 13.32P
13*32 Black-and-white photography is a commercial process that involves a phenol. Black-and-white film is coated with an emulsion containing silver bromide or silver iodide crystals that become activated by exposure to light. The activated silver ions then react with hydroquinone in the developing stage as shown in the following balanced equation.
All silver halide not activated by light is removed in the fixing process, and the result is a black image (a negative) left by the deposited metallic silver where the film had been struck by fight. In this

The exhaust systems of cars today are equipped with catalytic converters that uses rhodium and platinum as catalysts. No more than 4-9 grams of these precious metals are used in a single converter. This catalyst speeds up reaction of three types of toxic compounds given off the cars. The rhodium and platinum as catalysts do not enter into a chemical reaction, but the rough surface of the catalyst provides a high-surface area for the reaction to occur. Catalytic converters change unburned hydrocarbons, carbon monoxide, and nitrogen oxides into harmless compound.
Why is it not necessary to add more rhodium and platinum to a catalytic converter as these substances are used?
Which of the following is an example of a catalyst?
dNTP's used as building blocks for a new DNA strand synthesized in a PCR reaction.
Enzymes in your saliva that increase the rate of the breakdown of food molecules
A compound that is produced in the final step of a reaction mechanism, and appears as a product in the net reaction.
Phenolphthalein indicator used in acid/base titrations.

- Substances that poison a catalyst pose a major concern for many engineering designs, including those for catalytic converters. One design option is to add materials that react with potential poisons before they reach the catalyst. Among the commonly encountered catalyst poisons are silicon and phosphorus, which typically form phosphate or silicate ions in the oxidizing environment of an engine. Group 2 elements are added to the catalyst to react with these contaminants before they reach the working portion of the catalytic converter. If estimates show that a catalytic converter will be exposed to 625 g of silicon during its lifetime, what mass of beryllium would need to be included in the design?arrow_forwardIdentify the first chemical step in the production of Portland cement. How is this reaction related to the chemistry that takes place in the carbonation of concrete?arrow_forwardYou probably know that on exposure to air silver tarnishes and iron rusts; but gold, stainless steel, and chromium do not change. Explain these facts, using the concept of stability.arrow_forward
- Silicon forms a series of compounds analogous to the al-kanes and having the general formula SinH2n+2. The first of these compounds is silane, SiH4, which is used in the electronics industry to produce thin ultrapure silicon films. SiH4(g) is somewhat difficult to work with because it is py-ropboric at room temperature—meaning that it bursts into flame spontaneously when exposed to air. (a) Write an equation for the combustion of SiH4(g). (The reaction is analogous to hydrocarbon combustion, and SiO2 is a solid under standard conditions. Assume the water produced will be a gas.) (b) Use the data from Appendix E to calculate ? for this reaction. (c) Calculate G and show that the reaction is spontaneous at 25°C. (d) Compare G for this reaction to the combustion of methane. (See the previous problem.) Are the reactions in these two exercises enthalpy or entropy driven? Explain.arrow_forwardIn a typical laboratory setting, a reaction is carried out in a ventilated hood with air circulation provided by outside air. A student noticed that a reaction that gave a high yield of a product in the winter gave a low yield of that same product in the summer, even though his technique did not change and the reagents and concentrations used were identical. What is a plausible explanation for the different yields?arrow_forwardThe following reversible enzymatic reaction occurs in many areas of the body, but especially in red blood cells. The conversion of water and carbon dioxide into bicarbonate and hydrogen ions occurs through the action of an enzyme called carbonic anhydrase. Use the Law of Mass Action to predict which direction this equation will go under different circumstances. CO2 + H2O ↔ H+ + HCO3- Hyperventilating would increase the loss of carbon dioxide (CO2) from the blood. In what direction would the reaction above go in order to restore equilibrium? Left or right?arrow_forward
