Combustion of hydrocarbons such as decane (C₁0H₂2) 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.

Write a balanced chemical equation, including physical state symbols, for the combustion of liquid decane into gaseous carbon dioxide and gaseous water. 2. Suppose 0.160 kg of decane 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.

esc 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 copper(II) chloride, which would react with silver nitrate solution like this: CuCl₂(aq) + 2 AgNO3(aq) → 2 AgCl(s) + Cu(NO3)₂(aq) C The chemist adds 90.0 mM silver nitrate solution to the sample until silver chloride stops forming. She then washes, dries, and weighs the precipitate. She finds she has collected 6.0 mg of silver chloride. olla Calculate the concentration of copper(II) chloride contaminant in the original groundwater sample.
