Laboratory III: Forces Problem IV: Normal and Kinetic Frictional Force I John Greavu March 13‚ 2013 Physics 1301W‚ Professor: Evan Frodermann‚ TA: Mark Pepin Abstract The dependence of two-dimensional velocity and position components on time as well as whether or not said components are constant was determined. Video was recorded of a ball being projected laterally and data of its flight were plotted. From analyzing the data and the corresponding graphs that followed‚ it was shown that while the

LAB 3.Ø.Ø: do ions combine in definite ratios PURPOSE The purpose of this investigation is to determine whether ions combine in definite ratios or not. To observe‚ and create a table of the different ions. QUESTION If copper (II) sulfate when mixed with sodium carbonate at different quantities combine to form ions in definite ratios. HYPOTHESIS / PREDICTION I believe that the ions will combine in definite ratios due to the fact that the valance electrons will not be changing throughout any

Reaction Paper: Forgiveness and Empathy The ability to be empathetic toward others and forgive is without a doubt essential to relationships between people. Loren Toussaint and Jon R. Webb ’s study "Gender Differences in the Relationship Between Empathy and Forgiveness" gives some insight into how gender may influence the frequency in the use of empathy and forgiveness. From the data collected from the study their also seemed to be a difference in the way empathy is linked to forgiveness in men

AIM: I am carrying out an investigation to see which alcohol is the best fuel. I will do this by experimenting with different alcohols and setting them alight and measuring different factors. I will analyse all my results and try to discover patterns‚ which should help me to conclude which alcohol is the best fuel. PLAN ==== This is how my experiment will be set out: ========================================== Keeping this experiment a fair test ===================================

Purpose Determine which kinds of reactions involve electron transfer as the driving force. Background Redox (reduction-oxidation) reactions include all chemical reactions in which atoms have their oxidation state changed. So‚ when a metal and a nonmetal react‚ there is an ionic bond formed‚ which means one of them loses electrons while the other gains them. Since this reaction involves the exchange of electrons it is termed as a redox reaction. The oxidation states in a metal- nonmetal are simple

Edward Dickson CHE101 DS-01 Experiment Date 7/21/2013 Report Submitted 7/21/2013 Title: Experiment #8: Ionic Reactions Purpose: In this lab we will work with aqueous solutions of ionic substances and determine if they are soluble. If the solution appears milky than it is known as a precipitate reaction‚ meaning it is soluble‚ and that the ions separated and became surrounded by water. Precipitates in this experiment are electrically uncharged. To identify which compounds are

Chemical Kinetics: The Iodine-Clock Reaction: S2O82−(aq) + 2 I−(aq) → I2(aq) + 2 SO42−(aq) To measure the rate of this reaction we must measure the rate of concentration change of one of the reactants or products. Here‚ it is convenient to carry out a clock reaction involving the product I2. To do this‚ you will include (to the reacting S2O82− and I−) i) a small (but accurately known) amount of sodium thiosulfate‚ Na2S2O3‚ and ii) some starch indicator. The added Na2S2O3 does not interfere with

CONCENTRATION ON REACTION RATE The aim of this experiment is to find the effect of varying the concentration of iodide ions on the rate of reaction between hydrogen peroxide and an acidified solution of potassium iodide: H2O2(aq) + 2H+(aq) + 2I⁻ → 2H2O(l) + I2(aq) The course of this reaction can be followed by carrying it out in the presence of small quantities of starch and sodium thiosulfate solutions. As the iodine molecules are produced they immediately react with the thiosulfate ions and are converted

of Chapter 14 (Kinetics of a Particle : Work and Energy) and Chapter 18 (Planar Kinetics of a Rigid Body : Work and Energy) In the Mechanic Dynamics subject‚ monitored by Dr. Faisal Mohamad Ayob‚ I have learnt about the Kinetics of a Particle : Work and Energy of Chapter 14 and Planar Kinetics of a Rigid Body : Work and Energy of Chapter 18. Between these two chapters‚ I found out that they have some similarities and differences that can be compared. In Chapter 14 which is Kinetics of a Particle
