  • Al2o3 Composites Lab Report

    composite has been investigated. For that purpose, the PMMA samples with Al2O3 additive prepared with different percentages(0,15,25,35 and 45) wt.% and different thickness. The experimental results showed that the D.C electrical conductivity increased with increasing the alumina concentrations and temperature. Also the activation energy change with increasing of additional alumina. The dielectric constant, dielectric loss, A.C electrical conductivity are changed with change the concentration of…

  • Health Benefits Of Catalase

    Abstract: Catalase is an iron porphyrin enzyme present in high concentrations in humans and animals liver tissues. It is a peroxisomal enzyme that is responsible for destruction of toxic H2O2 released during certain metabolic processes.The activity of catalase can be determined by measuring the decrease in H2O2 concentration which is the substrate. Introduction: An enzyme is a large protein that acts as a biological catalyst which changes the rate of a reaction. It provides an active site…

  • Thiosulphate Lab Report

    Purpose To investigate the effect of temperature on the rate of the thiosulphate reaction. Hypothesis If the temperature increases, then the rate of the thiosulphate reaction will also increase. Variables Independent variable: Temperature change in each experiment, which will be varied by increasing the temperature by 10°C each time. Dependent Variable: Rate of reaction, which will be measured by measuring the time taken for the cross to not be visible. Constants: Concentration of HCl and…

  • Marie Curie And Dimitri Mendeleev's Impact On Modern Day Science And Society

    What is a chemist? A chemist is a scientist that studies, physical and chemical properties of different forms of matter. There are two profound chemist whose findings were crucial to today's understanding of chemistry. There names were Marie Curie and Dimitri Mendeleev, both chemist made significant impacts on modern day science and society. Dmitri Mendeleev is responsible for the creation of the periodic table, while Marie Curie is responsible for discovering radioactivity, which advanced the…

  • Potato Enzyme Lab Report

    studied information about chemical reactions and how a catalyst is used to speed up reactions. We have learned that enzymes (proteins) in eukaryotic cells work as a catalyst to make this possible. Each enzyme in a eukaryotic cells has specific molecules it binds to, as they have a specific frame work. This specific frame work of the enzyme is known as the active site, designed to fit very specific substrates (molecules). This creates the enzyme-substrate complex where the chemical reaction…

  • Modified Organo Nannoclay Case Study

    In this study, we use the modified organo nanoclay as a new sorbent for separation and preconcentration trace amounts of Au(III) in aqueous solutions. Nanoclay was modified with 5-(4'-dimethylamino benzyliden)-rhodanine. Modified nanoclay was used as a solid sorbent for separation and preconcentration trace amounts of Au(III) ions. The sorption of gold ions was quantitative in pH range of 2.0 to 6.0, whereas quantitative desorption occurs instantaneously with 6.0 mL of 1.0 mol L-1 Na2S2O3. The…

  • Redox Catalyst Essay

    1. Redox Catalyst Catalyst is defined as a substance that increases the rate of a chemical reaction without changing its chemical composition and affecting the standard Gibbs free energy, by lowering the activation energy of a chemical reaction. It does so by providing an alternative reaction pathway. In redox reaction, the key chemical event is the net movement of electrons from one reactant to the other. The oxidation state of atoms are changed. Transition metal is used as redox catalyst due…

  • Essay On Zinc

    all foods. zinc is a bluish-white shiny metal if it is in pure form. Zinc has many uses in industry in Metallic form. Alloys such as brass and bronze are form by mixing of metallic zinc with other metals. Zinc form salts as it combines with other chemicals. In nature, most zinc ore is found as the salt of zinc sulfide. Sphalerite (ZnS) a element is found in association with other base metals such as copper and lead in ores. Sphalerite ore contain 60-62% zinc. It is the most heavily mined…
