You know that the temperature might get as low as 30. C, and you want to protect about 4.0 L water in the toilet tank from freezing. Calculate the volume of ethylene glycol (density = 1.113 g/mL; molar mass = 62.1 g/mol) you should add to the 4.0 L water.arrow_forwardMagnesium ribbon reacts with acid to produce hydro- gen gas and magnesium ions. Different masses of magnesium ribbon are added to 10 mL of the acid. The volume of the hydrogen gas obtained is a measure of the number of moles of hydrogen produced by the reaction. Various measurements are given in the table below. (a) Draw a graph of the results by plotting the mass of Mg versus the volume of the hydrogen gas. (b) What is the limiting reactant in experiment 1? (c) What is the limiting reactant in experiment 3? (d) What is the limiting reactant in experiment 6? (e) Which experiment uses stoichiometric amounts of each reactant? (f) What volume of gas would be obtained if 0.300 g of Mg ribbon were used? If 0.010 g were used?arrow_forward

Assuming gasoline is 100.% isooctane, with a density of 0.692 g/mL, what is the theoretical yield of carbon dioxide produced by the combustion of 1.2 1010 gal of gasoline (the approximate annual consumption of gasoline in the United States)?arrow_forwardSolid ammonium chloride, NH4Cl,NH4Cl, is formed by the reaction of gaseous ammonia, NH3,NH3, and hydrogen chloride, HCl.HCl. NH3(g)+HCl(g)⟶NH4Cl(s) NH3(g)+HCl(g)⟶NH4Cl(s) A 4.18 g4.18 g sample of NH3NH3 gas and a 4.18 g4.18 g sample of HClHCl gas are mixed in a 0.50 L0.50 L flask at 25 ∘C.25 ∘C. Identify the limiting reagent. How many grams of NH4Cl will be formed by this reaction? What is the pressure in atmospheres of the gas remaining in the flask? Ignore the volume of solid NH4Cl produced by the reaction.arrow_forwardCombustion 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. = Larrow_forward
- 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. Be sure your answer has the correct number of significant digits. ____ Larrow_forwardNitrogen and oxygen gases react to form nitrogen dioxide, NO2, according to the following equation: N2(g) + 2O2(g) = 2NO2(g) 3.0 moles of N2 and 8.0 moles of O2 are combined in a chamber and allowed to fully react. How much of each gas is present in the chamber after the reaction? Also, is there a way to identify in a question which law I should be using in order to get my answers?arrow_forwardOn January 28, 2014, in Germany, a barn containing 90 cows exploded when a stray spark caught the methane trapped in the building on fire. The building was damaged and one cow was slightly injured with minor burns. Assume that the 90 cows were producing 250L of methane per day and that there was a 15 hour collection in the barn when it ignited. __CH4 + __O2 → __ CO2 + __H2O a) How many liters of methane was in the barn when it exploded? b) What mass of water was generated in the explosion?

- The great French chemist Antoine Lavoisier discovered the Law of Conservation of Mass in part by doing a famous experiment in 1775. In this experiment Lavoisier found that mercury(II) oxide, when heated, decomposed into liquid mercury and an invisible and previously unknown substance: oxygen gas. Write a balanced chemical equation, including physical state symbols, for the decomposition of solid mercury(II) oxide (HgO) into liquid mercury and gaseous dioxygen. Suppose 48.0mL of dioxygen gas are produced by this reaction, at a temperature of 100.0°C and pressure of exactly 1atm. Calculate the mass of mercury(II) oxide that must have reacted. Be sure your answer has the correct number of significant digits.arrow_forwardAutomobiles 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.arrow_forwardThe combustion of gasoline produces carbon dioxide and water.
