Determination of the Enthalpy for Decomposition of Hydrogen Peroxide Objective: To construct a coffee cup calorimeter‚ measure its calorimeter constant‚ and determine the enthalpy of decomposition and formation of hydrogen peroxide. Background: This experiment is a classic thermodynamics lab. In it‚ we attempt to measure the enthalpy (H) of a chemical reaction. The main obstacle is that this is a quantity that cannot be measured directly. It instead is observed as heat from one substance is transferred

Lab Report: DRILLING FLUID (MUD) DENSITY Objective: The aim of this experiment is to determine the mud density‚ specific gravity and hydrostatic pressure gradient for water-based-mud‚ WBM (Drilling fluid) using the OFITE mud balance. Theory: Drilling fluids are used during the drilling of boreholes‚ either for oil wells or water boles holes. One of the major functions of a drilling fluid includes providing hydrostatic pressure to prevent formation fluids from entering the wellbore. To ensure

Wakeboarding Wakeboarding was invented by a San Diego surfer named Tony Finn. Tony began a wakeboard revolution in 1985 when he developed his cross between a water ski and a surfboard. Then‚ the owner of H.O. Sports‚ a leading water ski manufacturer took interest in advancing it by introducing the first compression-molded-neutral-buoyancy wakeboard. He called it the Hyperlite. This wakeboard led to the growth of the marketplace making wakeboards more accessible to everyone. How a Wakeboard Works

Calorimetry: Enthalpy of Neutralization Introduction: The purpose of this lab experiment was to determine the molar concentration of the unknown HCl by using a coffee cup calorimeter. A coffee cup calorimeter is made of Styrofoam cups with a thermometer that is placed from the top and into the calorimeter to measure the temperature as the reaction happens. The Styrofoam cup used for the calorimeter creates an isolated system as it acts as a heat insulator between the cup and the surrounding

Using Gibbs’ Reflective Cycle Gibbs’ Reflective Cycle (or Gibbs’ Reflective Model) Gibbs’ reflective cycle is a theoretical model often used by students as a framework in coursework assignments that require reflective writing. The model was created by Professor Graham Gibbs and appeared in Learning by Doing (1988). It looks like this: Action plan If it arose again what would you do? Descripiton What happened?
