A Step-by-step Guide to Understand the Process of ...

The entire process can be explained by a single chemical formula. 6CO2 +12H2O + Light → C6H12O6 + 6O2+ 6H2O. While we take in oxygen and give out carbon dioxide to produce energy, plants take in carbon dioxide and give out oxygen to produce energy. Photosynthesis has several benefits, not just for the photoautotrophs, but also for humans and ...

The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.
