Scandinavia. This element belongs to group 3 which consists of transition metals and Scandium shares this group with the element Yttrium. There are 4 groups in the periodic table and they are: metals, non metals, transition metals and gases. The chemical properties of Scandium are very similar to the rare earth elements. It reacts very quickly with acids and when reacting with oxygen, it tarnishes and burns to form Scandium oxide.…

Group Members Zoe Ching, Juliet Contreras, Ailly Lam, Aleksi Ska. Background information Enzymes are biological catalysts, which speed up the rate of chemical reactions. The pancreas produces a concentrated solution containing a mixture of enzymes – amylase, lipase and protease. In this experiment you will examine the effect of protease on casein, the protein found in milk. When the protease breaks down the casein, the opaque solution will become transparent. Theoretically, Enzyme activity…

Coffactors Abstact Chemical reaction are a part of every ones life there no dening it this fact. But is there a way to increase these reations and make processed like reasperation and metablolism faster. That is exactly what cofactors are beleived to do, increasing the rate of reaction. In this experirment lactase, ONPG, EDTA, and phosphate buffer are used to determine wether or not cofactors really increase the rate of chemical reation. To measure the reaction a spectrometer will be used.…

Introduction/Purpose: Chemicals all perform different reactions when dissolving into different chemicals, and in the lab “Our First Lab” my group and I observed one of these chemical reactions. The purpose of the lab was to witness the chemistry behind these reactions in action, so we could put research and observations together on how it was possible for something to illuminate with only a forced bend to it. Observed how each light sticks glow depended on the temperature they were exposed to,…

a site upstream from Goomboora Park. This site will be referred to as, Site 1. Measurements from Site 1 will be analysed and compared to water qualities recorded from previous years (2012, 2013, 2014, 2015). Water is a triatomic molecule, with a chemical formula of H20. At a temperature…

This problem is important because when new elements and compounds are discovered, scientists can figure out their characteristics They do this using KMT (Kinetic Molecular Theory). KMT states that in the substance as a gas behaves like hard, spherical objects that are always in constant motion with no attraction. The stated information is the staple of multiple gaseous theories. Some examples are frequency…

Abstract. The theoretical treatment of the equilibrium structure of the derivatives was based on the DFT method using the functional B3LYP with the base 6-311 ++ G (d, p). To distinguish the molecular electrostatic potential surface (MESP), we used the principle of HSAB (Hard Soft Acid and Base), in order to have the centers of activity of a molecule and the effects of substitution on the systems of pyrazolooxazine. These have anti-inflammatory activities. In our work, we have applied methods of…

Introduction Desulphurization of steel at ladle treatment of metal is one of the important technological operations. The successful course of the desulfurization process is provided by fire refining slag with specific chemical composition, usually based on calcium oxide. The duration of mixing of the metal with the slag in inert gas, the early formation of refining slag, then optimization of the metal oxidation providing the formation of iron oxide FeO in the slag to be less than 0.5 % able…

The Effect Of Temperature On The Rate Of Maggot Movement. Environmental Systems and Societies ---Planning Lab--- Gaurav Iyer Research Question To what extent does the temperature affect the movement of Maggots? Introduction The Experiment aims to analyze the behaviour of the maggots. In this case, behaviour is defined as the way organisms respond to their environment. In the experiment, the orientation of the movement of organisms and gametes in response…

The Effect of Temperatures on Rate of Reaction of Alka-Seltzer Introduction: A. Background This particular experiment consists of a purpose of finding out the effect of various temperatures on the rate of reaction of the Alka-Seltzer tablets. Alka-Seltzer is a medical drug that acts as a pain reliever or an antacid, which helps neutralize stomach acidity, such as heartburn. Alka-Seltzer is a form of a baking soda which is also known as sodium bicarbonate, (NaHCO₃). When sodium bicarbonate…
