Chemistry Internal Assessment: Determining the Enthalpy Change of a Displacement Reaction AIM: To determine the enthalpy change for the reaction between copper(II) sulfate and zinc. BACKGROUND THEORY: Bond breaking is endothermic while bond forming is exothermic. The reaction between copper(ll) sulfate and zinc is exothermic as the energy required to form the bonds of the products is greater than the energy required to break the bonds of the reactants. In an exothermic reaction‚ heat is

Experiment 1: Viscosity of Liquids Victoria Kulczak Lab Partners: Laina Maines & Heidi Osterman Date of Lab: 2/21/11 Due Date: 2/28/11 Abstract: The goal of this experiment was to determine the viscosity of given liquids. Two different methods were employed‚ the first measures time of flow of several methanol-water solutions‚ from point A to point B. The second method involves dropping a foreign object‚ in this case a sphere‚ into a cylinder of glycerol and measuring the time it takes for it to

Your Marbles to Discover a Liquid’s Viscosity Which Liquid Has the Highest Viscosity? In this project we will determine the viscosities of 5 separate liquids. The liquids we will test are corn syrup‚ honey‚ vegetable oil‚ milk‚ and water. We will find their viscosities by dropping a marble into each of these liquids and measuring the time it takes for it to reach the bottom. Before we conduct the experiment‚ we must first understand what viscosity is. “Viscosity is the quantity that describes a

Lab 3 Viscosity Measurement Arbnor Emini B1‚ acjz758@city.ac.uk Abstract The flow rates of a series of dilutions of glycerol solutions (100% glycerol and 98% glycerol concentration) were measured using a viscometer. The intrinsic viscosity of the solution was found along with other quantities such as shear stress and shear rate for example. The objective of this laboratory experiment was to measure and determine the viscosities of glycerol/water solutions using a rotational viscometer. Introduction
