Introduction: This investigation used spectroscopy to evaluate light absorption in different solutions. A spectrophotometer was used in the lab to determine these values. A spectrophotometer is an apparatus used to “measure the absorption of radiation in the visible and UV regions of the spectrum and allows precise at a particular wave length” (Jones et al.‚ 2007). The amount of light absorbed by a substance is directly in relation to the concentration of the solute and also the wavelength moving

SCI203 Phase 3 Lab Report Sources of CO2 Emissions Sharon Patton June 8‚ 2015 Colorado Technical University Purpose The purpose of this report is to determine the increase or decrease in CO2 emission over the past 40 years. Showing that human activity is the reason for the altering of the CO2 emissions to the earth. Resulting in the unbalancing of ecosystems across the globe. (M.U.S.E.‚ 2010) Introduction Carbon dioxide is naturally present in the atmosphere as part of the Earth ’s
