EBK INTRODUCTION TO CHEMISTRY
- Nitric acid is produced commercially by the Ostwald process, represented by the following equations: 4NH3(g)+5O24NO(g)+6H2O(g)2NO(g)+O2(g)2NO2(g)3NO2(g)+H2O(l)2HNO3(aq)+NO(g) What mass of NH3 must be used to produce 1.0 106 kg HNO3 by the Ostwald process? Assume 100% yield in each reaction, and assume that the NO produced in the third step is not recycled.arrow_forward3.88 One Step in the enrichment of uranium for use in nuclear power plants involves the reaction of UO2 with hydro- fluoric acid (HF) solution. The products are solid UF4 and water. Write a balanced chemical equation for this reaction.arrow_forward4.28 One of the steps in the manufacture of nitric acid is the oxidation of ammonia shown in this equation: 4NH3(g)+5O2(g)4NO(g)+6H2O(g) If 43.0 kg of NH3 reacts with 35.4 kg of O2, what mass of NO forms?arrow_forward
- Balance the following equations representing combustion reactions: a. b. c. C12H22O11 (s) + O2(g) CO2 (g) + H2O (g) d. Fe(s) + O2(g) Fe2O3(s) e. FeO(s) + O2(g) Fe2O3(s)arrow_forwardOne of the ways to remove nitrogen monoxide gas, a serious source of air pollution, from smokestack emissions is by reaction with ammonia gas, NH3. The products of the reaction, N2 and H2O, are not toxic. Write the balanced equation for this reaction. Assign an oxidation number to each element in the reactants and products, and indicate which element is oxidized and which is reduced.arrow_forward4.106 An ore sample with a mass of 670 kg contains 27.7% magnesium carbonate, MgCO3. If all of the magnesium carbonate in this ore sample is decomposed to form carbon dioxide, describe how to determine what mass of CO2 is evolved during the process.arrow_forward
