Question 1 1.1 Silica gel chromatography: This is known as the stationary phase in column chromatography. Firstly‚ the tapered exit of the column is sealed using porous material. This porous material serves as support for the packing material‚ and prevents it from exiting the pipe. Thereafter‚ silica gel is compacted into the glass pipe to make the separating column. In finishing preparation of the column‚ the solvent which is used as the mobile phase is then passed through the dry column. Then the

ENERGY MANAGEMENT PRINCIPLES INTRODUCTION In the modern days energy has the significant role in our life. With development where we got comfortable life and much modern facilities where we got some problem with excessive use of energy resources as declining of energy sources‚ climate change. So it is an big challenge for present and future generations as the cost of energy increase and its supply decrease‚ older buildings needs to modified and new buildings designed to use less energy. The optimization

The scientist’s problem statement is “What kind of substances make gel the strongest?” The independent variable will be the different additives (Table salt‚ citric acid‚ and sugar) which will be added using tablespoons. The dependent variable is the strength of the gel which will be measured using a scale of 10. The constant variable is the type of gel used and the amount of substance added to the gel which

The Energy of the Future The United States of America is in desperate need of an alternate energy source. One such alternate source is nuclear power. Nuclear power is a form of energy produced by an atomic reaction‚ which is capable of producing an alternative source of electrical power‚ replacing the energy currently supplied by coal‚ gas‚ or oil. This will help the United States move away from burning fossil fuels and potentially reduce overall pollution. Nuclear power has the potential to be
