5. Calculate the expected pH values of the buffer systems from the
experiments (a, b, c, d) using hte Henderson-Hasselbalch equation
shown in the background section. Use for the pke values: carbonic
acid= 6.37 and acetic acid=4.75

Why is permeable soil best for plants that need a lot of drainage?

Define dew point. i am writing this part to be able to ask the question

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.
