... hydrogen, one of sulfur and four oxygen. When dissolved in water, the molecules split into three parts, the two atoms of hydrogen separate and in the process each loses an electron, becoming a positively charged ion (H+). The sulfur atom and the four atoms of oxygen remain together as a sulfate group (SO4), and acquire the two electrons lost by the hydrogen atoms, thus ... ...

Abstract The goal of the soil project was to separate, purify, identify and quantify the four compounds that were present in an unknown soil sample. We were told that two of the compounds were organic and the other two were inorganic. We were given a list of all possible compounds, which we examined and used to create a procedure based on techniques we studied and practiced throughout the course that would allow us to perform both qualitative and quantitative analyses of our soil sample. We started our separation using vacuum filtration, first with ethyl acetate, and then water. This gave us a...
... , O3, CO2, and chlorofluorocarbons (CFCs) are measured in parts per million by volume (ppmv), parts per billion by volume (ppbv) or parts per trillion by volume (pptv). Atmospheric temperature and chemistry are believed to be controlled by the trace gases. There is increasing evidence that the percentages of environmentally significant trace gases are changing because of both natural and human factors ... ...
