“To get into the bowl or not to get in the bowl.” That was the question of the hour, as construction on Skittle Hive began, for it landed in the bowl it would be a reward with a glory and honor, not to mention a cool ten points. To do this many things had to be considered, such as elasticity constants, and the energy that was being used. Once that was done the catapult had to be made and tested on angle and how far it could firer. Then it was ready, ready to fire and reach for the skies or maybe…

Scientific Objectives The scientific objectives of the experiment were to measure the temperature of a sample of lauric acid as it 's cooled. The data was manipulated to generate a cooling curve and freezing point. Introduction Matter can be categorized as solid, liquid, or gas this is known as phases of matter. A solid is a sample of matter with a defined volume and a defined shape; this sample is not easily compressible and doesn’t flow smoothly. A liquid has an undefined shape and a fixed…

CHYMOTRYPSIN CATALYSIS Sarkis Hamalian ABSTRACT To examine the enzyme kinetics of chymotrypsin during the catalysis of the synthetic substrate p-nitrophenyl acetate (NPA). Initially, observe the magnitude of the initial burst with regards to the enzyme concentration. Secondly, the analysis of the steady state deacylation rate with regards to the pH of the reaction mixture. Chymotrypsin catalysis is a process that proceeds with two steps, an initial fast step involving the covalent modification…

Projectile Motion Worksheet A ball rolls off a desk at a speed of 3.0 m/s and lands 0.40 seconds later. How far from the base of the desk does the ball land? How high is the desk? What is the speed and angle of impact? A slingshot is used to launch a stone horizontally from the top of a 20.0 meter cliff. The stone lands 36.0 meters away. At what speed was the stone launched? What is the speed and angle of impact? A ball rolls with a speed of 2.0 m/s across a level table that is 1.0 m…

Examples and Solutions Example 1: Given Equation: MnO4- + S2-  Mn2+ + S0 Balance the equation by using the ion-electron method. Step 1 Oxidation: S2-  S0 Reduction: MnO4-  Mn2+ Divide into two half reactions. Identify the element that is being oxidized and the other being reduced. (Use the entire ion or molecule.) Step 2 Oxidation: S2-  S0 Reduction: MnO4-  Mn2+ Balance all the elements (other than oxygen and hydrogen). Step 3 Oxidation: S2-  S0 Reduction: 8H+ + MnO4- …

highly influenced on the reaction rate, when the particle size of the catalyst was decreased, therefore their surface areas was increased and the ratio of catalyst surface and reactant volume was playing a crucial role for controlling the reaction kinetics. The reaction was takes place on the surface of a substance, increasing the surface area should increases the quantity of the substance that is available to react, and will thus increase the rate of the reaction as well. The size and shape of…

4. Results and discussion 4.1 Material removal rate The material removed from each coupon was determined by measuring its mass before and after electro-polishing. Theoretical values were then obtained using Faraday’s laws of electrolysis as shown in Equation 9. (9) Where m is the mass of material removed in grams, I is the current and t is the electro-polishing time. EW is the equivalent weight which depends on the chemical composition of…

5.2.2.2 Interpretation of Regression Model The above equation can be written as D ∝ P^0.058/(V^(-0.117) 〖D_b〗^(-0.133) ) By observing the above equation we can say that the LAZ Depth is directly proportional to the Laser Power and inversely proportional to the Scan Velocity and Beam diameter. The observations of the model can be summarized as below: As Laser Power increases the LAZ Depth of workpiece surface will also increase. This is because the heat input to the workpiece is increasing…

Experiment 3: Buoyancy Introduction Mass is described as the measure of the amount of matter contained in an object. On the other hand, weight is the measure of the force of gravity acting on the mass. Mass is measured in kilograms, while weight is measured in newtons. The density of an object is found by dividing the mass by the volume. Buoyancy is the upward force of a liquid which counters the weight of an immersed object. The theoretical buoyancy of an object can be calculated by using the…

I: Introduction: a. background information- Physical Changes are changes that do not involve a change in molecular structure. They can be identified by a change in size, a change in shape, or a change in the state of matter. Chemical changes are changes that involve the re-arrangement of atoms in the molecule. They can be identified by a color change, if a new gas is given off, if a precipitate or new solid forms, and if light, electricity, or heat is given off. b. observations- The observation…
