(b) Gasohol can be a mixture of 10 mL ethyl alcohol and 90 mL of gasoline. How many grams of fructose are required to produce the ethyl alcohol in one gallon of gasohol?A website promoting the use of alternative energy vehicles and hybrid technologies claims that, "A typical automobile in the USA uses about 4040 gallons of gasoline every month, producing about 750 lbs of carbon dioxide." To determine the truth of this statement, calculate how many pounds of carbon dioxide are produced when 40.0040.00 gallons of gasoline are subjected to complete combustion. Assume that the primary ingredient in gasoline is octane, C8H18(l),C8H18(l), which has a density of 0.703 g/mL.Combustion of hydrocarbons such as undecane (C11H24) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide. 1. Write a balanced chemical equation, including physical state symbols, for the combustion of liquid undecane into gaseous carbon dioxide and gaseous water. 2. Suppose 0.310kg of undecane are burned in air at a pressure of exactly 1atm and a temperature of 18.0°C. Calculate the volume of carbon dioxide gas that is produced. Round your answer to 3 significant digits. = L
- For the following problem you should describe in complete sentences the steps you would take to solve the problem and indicate what information you obtain in each step. You do not need to find a numerical answer. You might want to use dimensional analysis to show that your answer has the correct units. Each year in the spring rhododendrons should be fertilized. The recommended fertilizer is described as 10-8-6, which means 10% N, 8% P2O5 and 6% K2O by mass. How many grams of ammonium nitrate (NH4NO3) would you need to produce 1 kg of fertilizer that is 10% N? You do not need to consider the other compounds that are necessary to provide phosphorous and potassium.Automobiles are often implicated as contributors to global warming because they are a source of the greenhouse gas CO2. How many pounds of CO2 would your car release in a year if it was driven 110. miles per week? Gasoline is a complex mixture of hydrocarbons. In your calculations, assume that gasoline is octane (molecular formula C8H18) and that it is burned completely to CO2 and H2O in the engine of your car. Also assume that the car averages 27.3 miles per gallon and that the density of octane is 0.703 g cm-3.Combustion of hydrocarbons such as butane (C4H10) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide. 1. Write a balanced chemical equation, including physical state symbols, for the combustion of gaseous butane into gaseous carbon dioxide and gaseous water. _________________________________________________________ 2. Suppose 0.450kg of butane are burned in air at a pressure of exactly 1atm and a temperature of 14.0°C. Calculate the volume of carbon dioxide gas that is produced.
