Part G The compound iron oxide can exist with either iron(II) ions or iron(III) ions. Conduct Internet research to learn about the
differences between iron(II) oxide and iron(III) oxide. Give the chemical formula for each compound. Describe their
appearance and uses. Based on your findings, are these two forms of the same compound, or are they two completely
different compounds?

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.
