Introduction: Many people have always wondered about the outcomes of chemical reactions. In the experiment, ‘The change of mass during chemical reactions,’ focuses on the change of mass during a chemical reaction. It is known that a chemical reaction is a process in which one or more substances, the reactants, are converted to one or...

I. Introduction Seawater reverse osmosis (SWRO) is a promising, sustainable technology for desalination plants in Australia, as the environmental impacts of the process can be carefully monitored and managed. Treated water for consumption from a SWRO desalination plant in Darwin, would be required to meet many industry standards including but not limited to; The Australian...

1. Introduction The purpose of this investigation is to gain quantitative information of the reaction that occurs when Sodium iodide and Lead (II) nitrate are combined. Stoichiometry is the quantitative relation between the number of moles (and therefore mass) of various products and reactants in a chemical reaction (Washington University in St. Louis, 2005.). Chemists...

Chromatography research task: Many materials appear to have the same relation, relative position, or structure but actually they are just a combination of materials; a main example being black ink which is found in pens and it is a mixture of different coloured substances. On multiple occasions, these materials are allowed to separate by dissolving...

Chromatography is the process of separating a mixture. Chromatography is used for a varied amount of applications and industrial processes such as for the pharmaceutical industry, food industry, and in many other processes. In the Pharmaceutical industry it may be used for the separation of chiral compounds. Pharmaceutical companies also like to use it to...

Introduction And Abstract (# Chroma = Colour, # Graphy = Grafein (in Greek) = To write). Chromatography is a method used to separate components of a mixture and they undergo two phases, the stationary and mobile phase. The stationary phase is responsible for solids and the mobile phase is responsible for liquids and gases as...

“PESTEL Analysis is a vital administration tool that ‘Hydrogen Fuel’ initiative can use to break down inside and outside factors that impact the circumstances in Fuel Cells. PESTEL represents – Political, Social, Economic, Technological, Environmental and Legal components that have impact on the large-scale condition of the undertaking that it works in. Hydrogen Fuel works...

Titration report Introduction Titration is using the concentration of a known solution to find the concentration of an unknown solution (Chemed.chem.purdue.edu, 2018). In our case we tried to find out the concentration of hydrochloric acid using sodium carbonate solution. To help complete this experiment we used a fair few new pieces of equipment, for example...

Ethanol, also known as ethyl alcohol, is a clear and colorless liquid that can serve as an alternative fuel to non-renewable energy sources. More than 97% of gasoline in the US contains ethanol, usually in three different mixtures called E10 (10% ethanol and 90% gasoline), E85 (15% gasoline and 85% ethanol), and E15 (15% ethanol...

Summary Pigeons have been a common nuisance in the many cultural sites of Kathmandu valley. Due to presence of easy food availability, building ledges and low level of predator the number of pigeons have raised and with it, the problems associated with it has also increased. Beside health, economic and beauty issue caused by the...
