Titanium dioxide has mesoporous structure that act like a pathway for the electrons crossing through the cell. After dye absorbs light, it will release electrons and these electrons need to travel from cathode to anode, titanium dioxide is a conductor that helps electrons move. If we don’t use any metal, these electrons can’t travel through thus they can’t produce current. the higher the wavelength, the lower the frequency thus the lower the energy the dye will absorb to release an electron. We

Research Proposal: Optimum ENP for Oil Spill Remediation Literature Review Summary and Knowledge Gap Oil spill contains crude oil, small amount of heavy metal, refined and unrefined petroleum oil(Intertek, 2015). Due to these toxic chemicals, oil spill is an environmental issue and needs great attention because of its adverse effective in aquatic life and ecological balance. Use of nanomaterials in oil spill remediation is a novice approach. Oil and water separation requires technology with unique

Recently, water and food pollution are the important global concern in environmental protection and human health due to their numerous harmful activities. There are many pollutants producing by human day-by-day including nitrate, fluoride, pesticides, mercury, lead, arsenic, and nitrite resulting from oil spills, burning of the fossil fuels, dumping waste and sewage of factories, and etc. Among them, nitrite was widely used in the food industry, pharmaceutical and agriculture as an additive in foods

The purpose of this lab was to analyze the reaction between various metals and ionic compounds to test if they follow the Activity Series of metals. For the most part, our hypothesis was that when metals and ionic compounds (sulphates) were combined, they will react according to the Activity Series of metals. In our experiment we hypothesized that when magnesium metal and copper sulphate combines, it will produce an aqueous solution of magnesium sulphate and copper metal. When zinc metal and iron

For centuries, people have looked to burying and burning their bodies after they die. After all, they are considered ethical and “normal” by almost all cultures. However, these options do not give back to the earth in the way they should after the earth has fed us, drenched our thirst, built our homes, and given us a place to love; without it, we could not do any of these things. An ecologist named Susanne Wiigh-Masak from Sweden has given us an alternative that will not only help the earth but then

The antimicrobial applications of metal NPs is currently interview of the hour , is due to the growing microbial resistances to multiple antimicrobial agents and the development of resistant strains. Their high surface area to volume ratio compared to bulk material, provides a large active surface with large number of the low coordinate atoms, available to interact with microbial membranes or to release metal ions. Among the others metal NPs, the recent interest in the CuNPs is propelled by both

Introduction: The main purpose of this experiment is to determine the empirical formula of zinc iodide, and in addition, validate the law of conservation of mass by precisely determining the quantities of reactants and products. Empirical formula is the simplest type of chemical formula. The simplest ratio of the number of atoms of each element in the compound is determined by the empirical formal of a compound. Typically the ratio provided by the empirical formula contains whole numbers. On the

precipitate was allowed to settle to repeat the decanting process again. In the fourth reaction, 15 mL of 6.0 M sulfuric acid was added to the copper (II) oxide while stirring. The balanced equation for this reaction is as follows: CuO (s) + H2SO4 (aq) à CuSO4 (aq) + H2O (l) + SO2 (g) When the sulfuric acid was added to copper (II) oxide, the solution turned blue. This was due to the formation of aqueous copper (II) sulfate, which produced the copper ions to change the color of the solution

Empirical Formula Of Magnesium Oxide The goal of the assignment was to determine the empirical formula based on the reaction of Magnesium and oxygen. Empirical Formula is a calculation to find the lowest whole number ratio of elements within a compound. To find the empirical formula, first the student must assume that the total mass is 100g for each element if the problem given is a percentage, then convert mass to moles, after that, divide each mole by the lowest value of moles calculated
