The results obtained from the experiment would be used by the waste disposal company to find an alternative use to waste solution instead of disposing them. The company believed that is was possible to use the waste solutions to make valuable solids and use this as an avenue of increasing the profitability of the company. The aim of this experiment was to investigate whether it was possible to make valuable solids from waste solutions. After carrying a series of experiments that involved mixing the various waste solutions, a mixture of...

...barium and strontium. In order to remove... Natural Gas as Energy Source: Advantages and Disadvantages Natural Gas is a fossil fuel, just like petroleum. It is a mixture of hydrocarbon gases, which dominantly consists of methane. Methane, a hydrocarbon, makes up around 90% of natural gas composition. The remaining 10% is shared between other heavier hydrocarbons: ethane, propane and butane. During its extraction, propane and butane gases are removed from the natural gas to form Liquefied Petroleum Gas (LPG). LPG is distributed to those regions where natural gas distribution through pipelines is not possible, due to economic reasons. In its pure form it neither has color nor odor. The most common source...

But they failed to interpret the results properly. They could not identify the reason for the formation of two new elements when Uranium nucleus was bombarded with a neutron. But German scientists Otto Hann and Fritz Strassmann were successful in explaining the process. They have concluded that “if a massive nucleus like uranium...
