What are two evidences that would indicate that a double replacement reaction occurred?
The source of oxygen that drives the internal combustionengine in an automobile is air. Air is a mixture of gases, principallyN2(∼79%) and O2(∼20%). In the cylinder of an automobileengine, nitrogen can react with oxygen to producenitric oxide gas, NO. As NO is emitted from the tailpipe ofthe car, it can react with more oxygen to produce nitrogendioxide gas. (a) Write balanced chemical equations for bothreactions. (b) Both nitric oxide and nitrogen dioxide are pollutantsthat can lead to acid rain and global warming; collectively,they are called “NOx” gases. In 2009, the United Statesemitted an estimated 19 million tons of nitrogen dioxideinto the atmosphere. How many grams of nitrogen dioxide isthis? (c) The production of NOx gases is an unwanted side reactionof the main engine combustion process that turns octane,C8H18, into CO2 and water. If 85% of the oxygen in an engine isused to combust octane and the remainder used to produce nitrogendioxide, calculate how many grams of nitrogen…
Assuming gasoline to be pure octane, C8H18 (actually, it is a mixture of many substances), an automobile getting 22.7 miles per gallon would consume 5.10x10^23 molecules per mile. Calculate the mass of this amount of fuel. Mass = g Please provide only typed answer solution no handwritten solution needed allowed
What is the mole ratio of oxygen to carbon dioxide in the combustion reaction for propane?
Write the product for the result of dichlorine oxide (Cl2O) reacting with water (the product will have only 1 equivalent (atom) of chlorine in it). (Express your answer as a chemical formula) Cl2O+H2O --> ?
Combustion of hydrocarbons such as ethane (C2H6) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the earth's atmospher can trap the sun's heat, raising the average temperature of the earth. For this reason there has been 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 ethan into gaseous carbon dioxide and gaseous water 2. Suppose 0.460 kg of ethane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degrees celsius. Calculate the volume of carbon dioxide gas that is produced. Round your answer to 3 significant digits.
