Chemical reaction

enzyme is a protein that increases the rate of a chemical reaction by lowering the activation energy of the reaction. This enables the reactant molecules to intake sufficient amount of energy to reach the transition state. The reactant that an enzyme acts on is referred to as the substrate. After the substrate molecule binds to an enzyme to form an enzyme-substrate complex, the enzyme converts the substrate to products of the reaction. The reaction that is catalyzed by an enzyme is very specific meaning

substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. In simpler terms this is a certain substance that is procured from another living organism that is used by others to create a reaction out of another substance. Tyrosinase or TYR is what is called a oxidase or enzyme that catalyzes an oxidation-reduction with special interest with reactions containing oxygen on a molecular level all of this is for the controlling the making and production

Introduction In this chemical reaction, the magnesium will dissolve in the hydrochloric acid to produce hydrogen gas. This is because magnesium is higher than hydrogen in the reactivity series. Therefore, when the two reactants are combined, a displacement reaction occus and the magnesium displaces the hydrogen, forming magnesium chloride and hydrogen gas. Mg (s) + 2HCl (aq) -> MgCl 2 (aq) + H 2 (g) Magnesium + Hydrochloric acid -> Magnesium Chloride + Hydrogen

In this today’s lab, Percent Yield of Hydrogen Gas from Magnesium and Hydrochloric Acid, the purpose is to study the stoichiometry of H2 produced from the reaction between magnesium (Mg) and hydrochloric acid (HCl). The chemical equation for this reaction is Mg +2HCl -> MgCl2 + H2. It was predicted that 0.0029 moles of hydrogen gas would be formed from 0.07g of magnesium metal and 10 mL of hydrochloric acid. The hypothesis was proven correct based on an actual yield of 0.00299 moles of hydrogen gas

During the preparation of the, “Turning Pennies Green”, lab, students were asked to perform an experiment at home. The lab demonstrates what the effects of chemical and physical changes are. Students were asked go home, put two pennies in separate bowls, and label one bowl cup A, water and cup B, vinegar. Then, they were asked to place paper towels in the bowl. For cup A, water was to be poured in, but just enough to wet the paper towel inside, so the penny was not submerged. The same was asked

For the objective of executing a reaction that produces a gas, magnesium and hydrochloric acid were reacted together in a single displacement reaction. Hydrochloric acid (HCl) is a medical-friendly, water and acid soluble substance that can be commonly found in batteries and fireworks. Magnesium (Mg), on the other hand, is an alkaline earth metal with an atomic number of twelve. It is commonly used for medicinal purposes and in cattle feed and fertilizers. Magnesium can be very reactive, especially

In the experiment we were determining the chemical formulas for the hydrated, and dehydrated samples. The purpose of this was to asses our knowledge of chemical formulas, and how they relate to each other. We first obtained the molar masses of Copper, Chlorine, Hydrogen, and Oxygen from the periodic table in our books, and then weighed a crucible and placed approximately 1 gram of the hydrated substance in the crucible, and weighed it again. Then we heated the hydrated substance with a bunsen

Enzymes are biological catalysts, they have specific functions and structures that catalyze chemical reactions within the body. Without the catalysing of these reactions, they would happen inefficiently and too slowly to sustain life. (Science Museum, 2017) Each reaction needs small amounts of energy to get started, this is known as activation energy. To start a chemical reaction, an enzyme works by lowering the amount of activation energy needed. Enzymes are proteins and are specific for their

by our genetics and environments, the remaining 40 % is up to us. Psychologists have researched that when you are happy, certain hormones are release. The feelings we experience are nothing more than chemical reactions taking place in our body. So do you think money can be used to make this reaction happen? Can money really buy happiness? This world is full of wealthy people, such as the royal and billionaire. The question is, are they always happy? We cannot deny the fact that money
