What best explains how two oxygen atoms, each with six valence electrons, can bond with each other? One atom can lose two electrons so that the other atom can gain them and have eight valence electrons. One atom can lose four electrons to the environment so that a total of eight valence electrons remains. Each atom can share two electrons with the other so that each atom has eight valence electrons. Each atom can lose two electrons so that there is a total of eight valence electrons between the atoms.

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.
