Abstract: The following experiments were performed in order to identify an unknown compound. Through many experiments, and confirmation tests, it was concluded that the unknown compound was potassium sulfate (K2SO4). The experiments included testing for solubility, anions, and cations. There were a list of possibilities to begin working off of. This table represents the possible identities for the compound before experimentation began. Eventually after narrowing down the list of possibilities from

The Effect of Temperature on the Enzymatic Activity of Amylase Enzymes are biological molecules or proteins that act as catalysts and help complex reactions occur everywhere in life. The enzyme and the substrate are in the same area, closely together. The enzyme grabs on to the substrate at a special area called the active site. The combination is called the enzyme/ substrate complex. After this, the substrate is changed. It can either be broken down or combined with another molecule to make something

The first molecule of butane shown is antibonding, meaning that the carbon groups are 180 degrees apart. This is the most stable conformation of butane because there is no strain on the molecule. The second molecule of butane shown is eclipsed, the eclipsed molecule has torsional strain between the carbon hydrogen bonds making it less stable than the anti or gauche form. The gauche form is the second most stable configuration of butane where the two methyl groups are staggered 60° apart from each

1) Here are the rules (for the handbook) that we crafted regarding parking. Please review and let us know if they are acceptable. Article VI, Section 7 of the Condominium Bylaws allows for the Association to allocate or assign parking if there is a shortage or parking spaces. At the beginning of the rules, I would indicate that the parking rules are enacted to implement Article VI, Sections 5, 7 and 10 of the Condominium Bylaws and Article XI of the Condominium Bylaws. If you believe there

Introduction Coincidentally Sulphur is the 16th element on the periodic table, and the 16th most abundant element in nature (Kutney, n.d.). Yellow in colour, Sulphur, in it’s elemental state, forms an 8-member ring. Elemental sulphur initially forms monoclinic crystals with orthorhombic crystals forming within a day of cooling. This change in form effects the density; orthorhombic crystals have a 5% greater density, and melt temperature; a range of 113°-119° with complete melt only achieved

camping, diving, as a decoration, or just for fun. The only thing that needs to be done in order to make them glow is bend them. But there is something more deeply than just bending the glow stick. These glow sticks involve chemical reactions. The reaction of these chemicals causes a constant release of energy. Atoms in the materials are stimulated, causing electrons to get a higher energy level and then return to their normal levels. When they do this, they release energy as light. This process

Radiometric dating is when the amount of Carbon-14 is analyzed in a specimen that was once living compared to the amount of Carbon-14 in a sample that is currently living. The important information that radiometric dating is based on is that Carbon-14 has been produced at a constant rate in the upper atmosphere for all of time. Furthermore, the half-life of Carbon-14 is 5,730 years and it will never change. When an element has an atomic number greater than 82, it is radioactive. When the nucleus

non-specific and some are highly specific. The active site on an enzyme is where the chemical reactions occur. Substrates, which are the reactants, bind to the active site. For specific enzymes, only substrates that fit the three-dimensional shape and structure of the active site can bind with it. When a substrate binds with an active site an enzyme-substrate complex (ES) is made. Only the substrates undergo chemical changes while the enzymes remain the same and are used again. The lock-and-key model

Free radicals are chemical species that contain a singly occupied orbital. They are neutral and tend to be highly reactive and is a species with an odd number of electrons. When a bond is broken both electrons of that bond remained with one of the atoms but for the formation of radicals, one electron of the bond remains with each of the atoms called hemolytic bond cleavage. Our body generates free radicals reactive oxygen species and reactive nitrogen species by various endogenous systems, exposure

Enzymes inhibitors Enzymes are a biological catalyst that accelerates a chemical reaction without itself being affected by the reaction. Enzymes are helpful because they speed up reactions. According to George Shields, “Protein enzymes work by bringing the reactants in a chemical reaction together in the most favorable geometrical arrangement, so that bonds can be easily broken and reformed. This is possible because different enzymes have different three-dimensional shapes.” Another function
