Chemical equilibrium

with the enzyme catalase. Introduction This experiment is designed to test the role of temperature on enzyme activity. Enzymes are “molecules that function as biological catalysts” (Reece 2015). They act as catalysts by speeding up the rate of a chemical reaction by “lowering the activation energy needed for the reaction to begin” (Reece 2015). The enzyme being used in this experiment is catalase. Catalase is an enzyme that is found in nearly all living organism that are exposed to oxygen (Wikipedia

live/function. These two catalysts definitely have their differences, however also have some key similarities. They are the same because if they aren 't heated up, they both lower the activation energy, thus increasing the intensity and speed of the chemical reaction. The reason Enzymes are able to

Life is defined by all the living creatures on earth. Biology is a broad topic of the study of life. Biology contains many different types of subjects within it that may be studied, like terrestrial or aquatic animals, or viruses and diseases. Here I will be talking about twelve of the millions of parts: Characteristics of life and kingdoms, biomolecules, nature and the importance of water, cells, energy and the carbon cycle, cell division through mitosis and meiosis, the central dogma through DNA/RNA

Background: In this lab, we will be observing a chemical reaction dealing with enzymes. You may ask, what are enzymes? Enzymes are proteins produced by living cells. For example, you have enzymes in your digestive system to help you break down food. Without enzymes, organisms will not be able to survive. Enzymes act as catalyst in biochemical reactions and catalyst speeds up the reaction by lowering the amount of activation energy. Activation energy is required for reactants to react into products

006/7th Review of Literature A chemical reaction is the “communication” (or interaction) between elements (Green, 2012). Chemical reactions can happen naturally or can be caused by a person. They can even happen inside of a living being (Newmark, 2000). Some chemical reactions can just happen randomly and others need different amounts of energy for them to occur. Heat can provide chemicals with the energy for this to happen. For example, dynamite is extremely

Introduction The objective of this lab will be to proficiently separate a mixture, using filtration and evaporation. In this lab, a homogeneous mixture will be created, along with a heterogeneous mixture.The two mixtures will be mixed together, yet separated. Common substances will be mixed and then separated using two of the techniques already listed; filtration and evaporation. Theory If the salt, sand, and water mixture is separated successfully through filtration and evaporation, then the

Furthermore, stoichiometry helps to figure out the limiting reactants and the excess reactants. The limiting reactant is the reactant that limits the amount of product formed in the chemical reaction. Which also means the reaction will stop when all of the limiting reactant is consumed. In the other hand, excess reactant is a reactant that completely used up and it remains when a reaction stop when the limiting reactant. Moreover, stoichiometry can be used to figure out the actual yield which is

Distinguish between stable and radioactive isotopes and describe the conditions under which a nucleus is unstable Isotopes are atoms of the same element with different numbers of neutrons; BUT they have the same number of protons. In nuclear chemistry, isotopes are shown in the following form: • Chlorine-35 is written as 35Cl and Rubidium-85 is written as 85Rb Isotopes can be divided in two categories, radioactive and stable. Stable Isotopes are isotopes that are not radioactive. They have stable

When you hear about global warming many things come to mind. The greenhouse effect, pollution, carbon dioxide and of course, the earths temperatures rising. When people hear of the greenhouse effect do they actually know what it is. The suns UV rays hit the earth and 30% of the energy reflected back into space, 47% gets absorbed by gasses and turns into heat energy. The rest is shared between the water cycle, photosynthesis Some of the heat tries to escape back into the atmosphere but is trapped

Chemistry. He represents Albertus Magnus. Albertus Magnus was a saint in the 1200s. He was also a scientist. Key idea 2 The periodic are horses. They represent different elements on the periodic table. For example, Au, which is gold is a chemical element. Its atomic number is 79. In its purist form it is a bright, slightly reddish yellow, soft, dense and a ductile metal. Chemically gold is a transition metal and a group 11 element. Each horse is a different size, shape, and
