In this experiment‚ the coefficient of restitution between two balls‚ (a glass marble and a steel ball bearing) and the apparatus it is colliding with will be determined. AIMS To determine the coefficient of restitution between two balls‚ (a glass marble and a steel ball bearing) and the apparatus it is colliding with. THEORY When two bodies collide‚ equal and opposite forces act on each body and will cause a motion. If there

BIOLOGY LAB REPORT (UNIT 7: ENZYMES) GENERAL Enzymes are protein that acts as catalyst‚ lowering the activation energy need for reactions to progress in cells. The reaction can still occur without the presence of the enzyme‚ but at a much slower rate. The activation energy is the minimum amount of energy need for a chemical reaction to occur‚ yielding from a given set of reactants. In enzymatic reactions‚ we have substrates which are reactants of reaction bound to an enzyme. While an active site

Abstract By working with physical isopods‚ ordinarily known as pill bugs‚ sow bugs or roly- polies‚ we tried whether these sowbugs favored a dark spot to a light place. Included in the lab are a few outlines and tables sketching out our aftereffects of the test. We measured recurrence

ANALYSIS OF UNKNOWN ACID SAMPLE USING TITRATION METHOD Date of Experiment: 4 September 2012 Introduction An acid-base titration is a procedure used in quantitative chemical analysis to determine the concentration of either an acid or a base. Titration is the slow addition of an acid (or a base) of known concentration from a burette (a narrow graduated cylinder) to a base (or an acid) of unknown concentration fin an Erlenmeyer flask. There

Silver Fiddle Construction 1) Identify potential risks associated with this project. Try to come up with at least five different risks. Now that we have clearly defined the key aspects and variables associated with this project. A brief description of the risks I identified begins with Silver Fiddle’s practice of using subcontractors. * Silver Fiddle routinely subcontracts build work to local subcontractors. As previously discussed‚ Silver Fiddle is scheduled to build eleven homes this

Electrochemical Cells Lab Report AP Chemistry Block 1 Analysis: The purpose of Part 1 of this laboratory is to construct a table listing the reduction potentials of a series of metal ions in order of ease of reduction. The series of half-cells is constructed by placing a piece of metal into a 1.0 M solution of its ions for each metal in the series. The metals are Cu‚ Fe‚ Pb‚ Mg‚ Ag‚ and Zn. The half-cells are connected by a salt bridge constructed of a strip of filter paper soaked in a solution
