- 4.3 Explain the difference between complete and incomplete combustion.arrow_forwardOn Easter Sunday, April 3, 1983, nitric acid spilled from a tank car near downtown Denver, Colorado. The spill was neutralized with sodium carbonate: 2HNO3(aq)+Na2CO3(aq)2NaNO3(aq)+H2O(l)+CO2(g) a. Calculate H for this reaction. Approximately 2.0 104 gal nitric acid was spilled. Assume that the acid was an aqueous solution containing 70.0% HNO3 by mass with a density of 1.42 glcm3. What mass of sodium carbonate was required for complete neutralization of the spill, and what quantity of heat was evolved? (Hf for NaNO3(aq) = 467 kJ/mol) b. According to The Denver Post for April 4, 1983, authorities feared that dangerous air pollution might occur during the neutralization. Considering the magnitude of H, what was their major concern?arrow_forwardMagnesium metal (a component of alloys used in aircraft and a reducing agent used in the production of uranium, titanium, and other active metals) is isolated from sea water by the following sequence of reactions: Mg2+(aq)+Ca(OH)2(aq)Mg(OH)2(s)+Ca2+(aq)Mg(OH)2(s)+2HCl(aq)MgCl2(s)+2H2O(l)MgCl2(l)electrolysisMg(s)+Cl2+Cl2(g) Sea water has a density of 1.026 g/cm3 and contains 1272 parts per million of magnesium a5 Mg2+(aq) by mass. What mass, in kilograms, of Ca(OH)2; is required to precipitate 99.9% of the magnesium in 1.00103 L of sea water?arrow_forward

- Combustion of hydrocarbons such as undecane (C,H) produces carbon dioxide, a "greenhouse gas. Greenhaluse gases in the Earth's atmosahere tan trap the Sun's heat, raising the averege temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carban diaxide. 1. Write a balanced chemical equation, including physical state symbols, for the combustion of liquid undecane into pmequs carbon diocide and gaeous water. D-0 2. Suppose 0.300 kg of undecane are burned in air at a pressure of exatly I atm nd a temperature of 17.0 "C. Calculate the volume of carbon dionide gas that is produced. Round your answer to 3 significant digits.arrow_forwardThe decomposition of nitroglycerin (C3H3N;O,), a powerful explosive, may be represented by the reaction: C;HŞN3O9 – N2 + CO2 + H20 + O2 1. This reaction generates a large amount of heat and many gaseous products. The sudden formation of these gases, together with their rapid expansion, that produces the explosion. a) Balance the following reaction. Show proof of completion. b) What is the maximum amount of Oz in grams that can be obtained from 2.00 x 10° g of nitroglycerin? c) Calculate the percent yield in this reaction if the amount of O2 generated is found to be 16.55 g. 2. Ethyl chloride is prepared by the reaction of chlorine with ethane according to the following equation: C:Ho(g) + Cl2(g) → C:H$CI(g) + HC(g) Ethane Ethyl chloride a) Write the balanced chemical equation.
