Chemical reaction

In this experiment, solid magnesium was conducted in a chemical reaction with hydrochloric acid solution. The three objectives include: measuring the gas production of a chemical reaction by a pressure change, determining the mass of the hydrogen gas produced in the reaction, and determining the effectiveness of the procedure by calculating the percent yield. In order to complete these objectives, a flask containing the magnesium ribbon was completely submerged into a large beaker filled with…

world economy, the human body, and the environment, copper has been studied and manipulated to explore its uses and properties. In the experiment performed, the copper cycle was observed by placing copper through a series of chemical reactions to demonstrate the different reaction types. Materials and Methods To begin the experiment, a 50 mL beaker was placed on a hot plate with a ring stand along with a fume hood made out of a funnel, rubber tubing, and an aspirator. Before advancing through…

According to the American Chemical Society, many properties of clothing ranging from color to warmth to clothing’s elasticity is the work of a textile chemist (2016). Textile chemistry allows us to create synthetic fibers to produce clothing that is finely tuned to a certain situation…

of metabolic chemical reactions, from the digestion of food to the synthesis of DNA. Enzymes catalyze chemical reactions involving the substrate. Substrate is a molecule that attach to the active site of the enzyme protein which an enzyme acts. Active site is a small port in an enzyme that helps enzyme to bind with substrates and undergo a chemical reaction. During this binding of substrates with active site it creates enzyme substrate complex, which is the complex where the reaction occurs. A…

Single Replacement Reactions and Double Replacement Reactions A chemical reaction is a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction. The evolution of energy as heat and light, production of gas, formation of a precipitate, and color change are 4 indicators of a chemical reaction. Two out of the six types of reactions are the single and the double replacement reactions. During single…

pressure increases the concentration of gas molecules, which in turn speeds up the reaction (Brown, 2000). When the temperature is decreased the position of equilibrium is moved to the right, which also results in more ammonia with a higher yield, as heat is released in this equation this is a exothermic reaction (AUS-e-TUTE, 2014) this change of heat in a system is known as enthalpy. The reaction is exothermic as the reaction favors the low temperature. More ammonia gas is produced because the…

area on the reaction rate. Introduction: In this experiment the experimenters will seek to determine what factors determine the rate of a reaction with a catalyst. A catalyst is a molecule that starts a chemical reaction, but it is not part of the reaction it is causing. The experimenters will use pieces cut up potato as an organic catalyst. The potato contain enzymes that will perform the reactions. Enzymes, “are proteins, produced by living cells; they catalyze chemical reactions by lowering…

Tyler White CHEM151LL 13851 07/18/2017 Mole to Mole relationship and Empirical formula of a Hydrate Purpose: The purpose of this lab experiment is to determine the molar ratio between substances, and to write chemical equations. The second experiment is to determine the ratio of water in copper, and magnesium, which is obtained through burning the vapor using the Bunsen burner. Materials: Because the experiments were conducted online there wasn’t any use of materials, only digital ones, for…

Temperature. Normally an increase in temperature will lead to an increase in the rate of a chemical reaction, but the reaction rate will decline after it passes the optimum temperature, meaning the temperature at which the activity of the enzyme and the rate of the reaction is the highest. Any temperature higher than optimal will chance denaturing (loss of biological function) the enzyme and lowering the reaction rate. Alkaline Phosphatase is an enzyme found in the human body and as such is…

Information: Enzymes are catalysts for chemical reactions in living things, they help the body speed up the rate of virtually all of the chemical reactions that take place within cells.They are very important, enzymes are biological catalysts. Enzymes don’t need a lot of energy to start a chemical reaction, it all depends on the body's temperature. Enzymes need catalysts, catalyst is a substance that decreases the activation energy needed to start a chemical reaction. Enzymes are very…
