- Propane, C3H8, is a hydrocarbon that is commonly used as a fuel. (a) Write a balanced equation for the complete combustion of propane gas. (b) Calculate the volume of air at 25 C and 1.00 atmosphere that is needed to completely combust 25.0 grams of propane. Assume that air is 21.0 percent O2 by volume. (Hint: we will see how to do this calculation in a later chapter on gasesfor now use the information that 1.00 L of air at 25 C and 1.00 atm contains 0.275 g of 2 per liter.) (c) The heat of combustion of propane is 2,219.2 kJ/mol. Calculate the heat of formation, Hf of propane given that Hf of H2O(l)=285.8 kJ/mol and Hf of CO2(g)=393.5 kJ/mol. (d) Assuming that all of the heat released in burning 25.0 grams of propane is transferred to 4.00 kilograms of water, calculate the increase in temperature of the water.arrow_forwardCompare the greenhouse gases and final temperature for each scenario.

Photochemical smog is a type of air pollution in the troposphere of our planet produced when sunlight acts upon motor vehicle exhaust gases to form harmful substances such as ozone (O3). For example, nitrogen dioxide (NO2) reacts with atmospheric oxygen (O2) in the presence of light to produce ozone (O3) and nitrogen monoxide (NO).arrow_forward

- The atmosphere slowly oxidizes hydrocarbons in a number of steps that eventually convert the hydrocarbon into carbon dioxide and water. The overall reaction of a number of such steps for methane gas is:CH4(g) + 5 O2(g) + 5 NO(g) ------> CO2(g) + H2O(g) + 5 NO2(g) + 2 OH(g) Suppose that an atmospheric chemist combines 155 mL of methane at STP, 885 mL of oxygen at STP, and 55.5 mL of NO at STP in a 2.0-L flask. The flask stands for several weeks at 275 K. If the reaction reaches 90.0% of completion (90.0% of the limiting reactant is consumed), what is the partial pressure of each of the reactants and products in the flask at 275 K? What is the total pressure in the flask?arrow_forwardMatch each pollutant with their final product in our atmosphere. > SO₂ NO₂ CO CH4 1. CO2 2. H₂SO4 3.

- You are heating potassium perchlorate and collecting the oxygen gas from the decomposition over water. Write the equation here! 2 KClO3(s) ----------> 2KCl (s) + 3O2 (g) 2. Mass of sample: 0.398 g Ambient pressure: 752.3 mmHg Volume of gas: 81.4 mL Room temperature: 18.9 degrees Celsius 3. Using the mass of your KClO4 sample, and the balanced equation, calculate the theoretical yield of O2 gas in grams. 4.
