Hypothesis: I can successfully add vectors. Introduction: A vector is a quantity that has magnitude (speed, force, and/or length) and direction. For example, if a person is traveling East at 60 mph, then s/he is traveling in the direction East and at a magnitude of 60 mph. A scalar is a quantity with only a magnitude. Common scalars include currency, mass, time, and acceleration. It wouldn't make sense to say the sweater costs $38.00 southwest,

Lab Report - Time Perception In An Altered State Of Consciousness
Abstract This study explored the question of whether people who say they are skilled at relaxation report a deeper level of relaxation than people who say they are not so skilled. Undergraduate psychology students (37 males and 127 females, mean age 20 years) followed one of three different sets of instructions that detailed how they were to relax, and after doing so for a period of time, completed a survey where they rated on a

Catalase Lab Report
An enzyme is a tertiary globular protein. The function of an enzyme is to lower the activation energy of either the creation or breaking apart of a chemical bond. By lowering the activation energy of this process, the reaction of bonding, or in this case breaking apart, is sped up. An enzyme breaks apart the substrate in the active site of the enzyme; this is where the magic happens. Substrate is what is being broken

Wave Nature of Light Objective: The purpose of this lab is to investigate interference, otherwise known as the diffraction of light. A beam of light acts a wave, and we are able to use equations so calculate the wavelength of the light used. The diffraction of a straight edge demonstrates that light waves bend around straight edges, allowing light to enter an area of shadow. When waves are superposed, they reinforce each other when crests

Organic Lab Report: 1-Bromobutane from 1-Butanol, Incomplete
PREPARATION OF 1-BROMOBUTANE FROM 1-BUTANOL VIA SN2 REACTION By: A. Nguyen (991414) ABSTRACT: 1-bromobutane was synthesised from 1-butanol with sodium bromide and sulfuric acid via nucleophilic substitution (SN2 mechanism). Conversion of the functional group in butanol, -OH to a better leaving group, required a catalyst in which sulfuric acid was used. In order for 1-bromobutane to be synthesised methods of purification including refluxing, simple distillation and separation was carried out. The end product of 1-bromobutane

________________ Introduction: A transfer of energy in chemistry is usually measured by heat. This heat change often indicates a chemical reaction taking place. The enthalpy of reaction can be calculated from measuring this heat transfer. By using the enthalpy of reaction, other information concerning the reaction reactant and products can be derived. For example, this information can be used to determine whether the reaction is endothermic or exothermic. The main objective of this lab is
