Chemical reactions

metals to gold through chemical reactions, physical reactions, radioactive decay, or nuclear fission, it is possible to change them through nuclear fusion. Common metal such as copper cannot go through physical reactions to turn into gold because the substance would only change phase. A physical reaction is the rearrangement of molecules…

Kinetic can be defined as a study of the speeds or the rates of chemical reactions. The factors that could affect the rates of the reactions are physical state, reaction temperature, catalysts, pressure, concentration of solution, and reaction time. The change of the speed of the reaction can be predicted based on the different reaction conditions. Kinetic study is important because it can describe information about the reaction mechanism. The concentration has affected the frequency which the…

Research Question How does the increase of concentrated hydrochloric acid affect the rate of the chemical reaction with sodium thiosulphate? Background to the Research question Chemical reaction involves the chemical change of atoms and molecules, it will occur when two or more molecules interact with each other and the molecule will change. Thus, bonds between atoms are broken down and then new molecules are formed. Hydrochloric Acid and Sodium thiosulfate are both colourless and clear…

(2003) Paragraph 1 Crystal chemical relationship between quartz (SiO2) and FePO4 Silicon dioxide is an oxide of silicon with the chemical formula of SiO2. SiO2 is a chemical compound most commonly found in Quartz and it has a space group of P3121. The lattice symmetry of SiO2 is tetrahedron, where there are 4 oxygen atoms covalently bonded to the silicon atom, as shown in Figure 1. Figure 1 - Structure of Silicon dioxide Iron (III) phosphate is a compound with the chemical formula of FePO4.…

Chemical reactions Sabatier’s reaction When hydrogen combines with carbon dioxide at around 350 Celsius in the presence of alumina, ruthenium or nickel catalyst, it gives methane and water. CO2 + 4 H2 → CH4 + H2O This reaction can be used to produce water in empyreal. CO2can be extracted from mars and the waste from the industrial torus where there is high levels of CO2 H2 can be obtained from electrolysis The methane can be used as a fuel in industries. GRAVITY Empyreal has a torus…

Introduction: A reversible chemical reaction is a reaction which can proceed in both the forward and backward directions which can be represented by the symbol . A reaction comes to equilibrium when the rate of reaction of the reactants is equal to that of the rate of reaction of the products. An example of a reversible chemical reaction is one which occurs in the pool between chlorine and water (Deb Smith, 2006). Equation 1 A reaction takes place with water to produce hypochlorous acid, HOCL…

Concentration on Reaction Rates and Pressure Background - While conducting the Enzyme Lab, students used enzymes as catalysts in order to speed up the reaction processes involved in several tests. Enzymes are substances produced by living organisms that act as a catalyst, while a catalyst is a substance that increases the rate of the chemical reaction. Furthermore, varying amounts of pH and enzymes were added to the mixture in order to determine the substance’s rate of reaction. When the…

Introduction Actual rocket ships use chemical reactions to lift off into space. Using baking soda and vinegar we can simulate a rocket taking off because when mixed together, a chemical reaction occurs. By changing the amounts of the chemicals we can determine which will allow the bottle rocket to go farther. Chemical Reaction Vinegar is an acetic acid. When an acetic acid and baking soda (sodium bicarbonate) are mixed together, three new chemicals are formed, Water (H2O), carbon dioxide (co2),…

of this experiment is to get a better understanding of limiting reactants and chemical reactions as whole. It also helped us determine how the amounts of sodium carbonate and calcium chloride affect the chemical reaction made: calcium carbonate. Introduction: This lab was to show the relationship between reactants and products. In this case, we used calcium chloride and sodium carbonate. This made a chemical reaction and eventually formed calcium carbonate. The goal of this lab was to…

energy changes lab was an interesting lab in which the class compared two chemical reactions, the solute baking soda and the solvent vinegar, and the solvent baking soda solution with the solute of calcium chloride to see whether the changes were endothermic or exothermic reactions. I concluded that vinegar and baking soda was the endothermic reaction and baking soda solution and calcium chloride was the exothermic reaction. I knew this because in the vinegar and baking soda, the temperature…
