Store equal amount of tap water in a glass jar and in a single-use water bottle for 2 weeks in normal room temperature. Test the pH strength of the water in both cases using a pH paper and compare the results and arrive at conclusions.

What is the number of atoms in 3.54 mol s

How do scientists think that gravity affected the formation of our solar system?

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.
