    Measuring Human Reaction Time Name: Prerna Mohan Date: November 3‚ 2017 Team members: Allison Fitzgerald‚ Isabella Federico 1. Objectives The objective of this lab is to measure each individual’s reaction time using a ruler. 2. Method and Equation: We will apply free fall kinematics to find our own reaction time. An object in free fall is an object in motion where gravity is the sole force acting upon it. If we drop an object from a certain distance‚ the object will experience constant

    Introduction The purpose of this experiment is to determine the rate equation for the “Iodine Clock Reaction” experiment. The experiment will consider the equations 〖2I〗^-+S_2 O_8→2〖〖SO〗_4〗^(2-)+I_2 and I_2+2〖S_2 O_3〗^(2-)→2I^-+S_4 O_6 in order to determine the rate law of Rate=k[〖〖S_2 O_8〗^(2-)]〗^a 〖[I^-]〗^b by using the experimental data to calculate the values of exponents a and b as well as the rate constant k. Experimental Supplies Needed: 250 mL Erlenmeyer flask‚ 100 mL beaker‚ graduated

    4-Nitroaniline Lab Report

    4-nitroaniline had a percent recovery of 18.67% and naphthalene had a percent recovery of 80%. Naphthalene had a relatively high percent recovery‚ and the loss of product can be explained by error inherent. The low percent recovery of 4-nitroaniline is mainly due to the fact that anhydrous sodium sulfate was accidently added to the flask. Therefore‚ some product was lost as the aqueous solution with the protonated 4-nitroaniline reacted with the drying agent. However‚ more errors to explain the results

    Ionic Bonds Essay The periodic table is a masterpiece of organized chemical information. It is a table of the chemical elements in which the elements are arranged by order of atomic number. The standard form of the table includes periods (horizontal rows in the periodic table) and groups (vertical rows in the periodic table). Atoms are the basic building blocks of ordinary matter. Atoms are made up of particles called protons‚ electrons‚ and neutrons. Protons carry a positive electrical charge‚

    laboratory assignment 3 was to measure the rate at which a chemical reaction takes place. For the purpose of this lab we measured the rate a balanced oxidation/reduction reaction between iodine‚ hydrogen‚ and bromate ion occurs. The above reaction occurs slowly so we used a coupled iodine clock reaction to measure the rate of the oxidation/reduction reaction because it occurs much faster but is still dependent upon the other reaction. To accomplish this‚ two mixtures were prepared in separate Erlenmeyer
