Combustion of hydrocarbons such as pentane (C,H,,) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the 131 12 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. 1. Write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. ローロ do x10 2. Suppose 0.210 kg of pentane are burned in air at a pressure of exactly 1 atmn and a temperature of 14.0 °C. Calculate the volume of carbon dioxide gas that is produced.

UV Visible Spectroscopy

Spectroscopy refers to the absorption or emission of light or other radiations by matter. When a substance or chemical absorbs light or radiation, they reach an excited state followed by de-excitation or emission of the light or radiation forming distinct spectra. UV-visible spectroscopy or  ultraviolet-visible refers to the absorption and emission in the ultraviolet and visible regions of the electromagnetic spectrum.
