past failed societies and determines that societies that have failed or will fail‚ do so because of a combination of factors. These factors include environmental damage‚ climate change‚ hostile neighbors‚ friendly trade partners‚ and primarily‚ how the societies respond to their problems (Diamond p.11). Applying water pollution‚ to Diamond’s proposed‚ "five-point framework‚" explains that water pollution’s implications contribute directly and indirectly to a possible collapse of society.

The Inorganic Chemistry of Carbon Inorganic Carbon For more than 200 years‚ chemists have divided compounds into two categories. Those that were isolated from plants or animals were called organic‚ while those extracted from ores and minerals were inorganic. Organic chemistry is often defined as the chemistry of carbon. But this definition would include calcium carbonate (CaCO3) and graphite‚ which more closely resemble inorganic compounds. We will therefore define organic chemistry as the study

The data we recorded was that bubbles formed on pencil led‚ and one of the batteries anodes turned slightly yellow. The reaction was H20- 2H (g) + O2. The next station was at number four. The procedure was to hook one mechanical pencil lead to each of the
