Combustion of hydrocarbons such as pentane (C3H12) 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 pentane into gaseous carbon dioxide and gaseous water. 2. Suppose 0.420 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 11.0 °C. Calculate the volume of carbon dioxide gas that is produced. Round your answer to 3 significant digits.

The combustion of 1.66 g ultrafine aluminum in air results in 2.97g of a product, which is a mixture of 80 % aluminum oxide and 20% aluminum nitride (% by mass) Use the empirical formula of aluminum oxide and find the formula for aluminum nitride. Report the molar amount of aluminum oxide: ттol so that the molar amount of aluminum in the nitride can be found as: тmol and the molar amount of nitrogen is: ттоl so that the ratio of aluminum to nitrogen can be found to be: а.и.
21. (a) Write the balanced chemical equation for the combustion of propane (C3H3). How does the potential energy change between the reactants and products in this reaction? (b) Draw a potential energy diagram for this chemical reaction. (c) What is the relationship between these energy changes and the breakdown and/or formation of covalent bonds? Explain your ideas in at least two (2) sentences and remember to use vocabulary terms.
One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate. Suppose an EPA chemist tests a 250. mL sample of groundwater known to be contaminated with iron(II) chloride, which would react with silver nitrate solution like this: FeCl,(aq) + 2 AgNO3(aq) → 2 AgCl(s) + Fe(NO3),(aq) The chemist adds 10.0 mM silver nitrate solution to the sample until silver chloride stops forming. He then washes, dries, and weighs the precipitate. He finds he has collected 7.7 mg of silver chloride. Calculate the concentration of iron(II) chloride contaminant in the original groundwater sample. Round your answer to 2 significant digits. mg L

Combustion of hydrocarbons such as pentane (C5H₁2) 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 pentane into gaseous carbon dioxide and gaseous water. 2. Suppose 0.440 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 18.0 °C. Calculate the volume of carbon dioxide gas that is produced.
