Complex Ion Formation:Cu(NH3)42 Ecell, after adding 6 M NH3to the copper cell 0.77V. Use the Nernst equation to calculate the concentration of that free copper (II) ion that is in equilibrium with the complexed copper (II) ion, Cu(NH3)42 in the solution. Does the calculated value for the [Cu2 ] make sense (look up the Kf for the formation of Cu(NH3)42 ) and rationalize your findings)

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.
