I am in the lab seeing if adding sugar to water affects how long it takes the water to boil. In the first test I boil 100 mL of water only in a beaker over a Bunsen burner and observe it takes 5:15 mins to boil. Next I add 2 grams of sugar to 100 mL of water and stir to dissolve, then boil making sure everything is the same. This time it takes 7:05 mins to boil the sugar-water mix. Next I add 4 grams of sugar to 100 mL of water. This time it takes 10:35 mins to boil the sugar-water mix. What could we infer about the effect sugar has on the boiling time of water?

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) 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.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
