Heats of Reaction – Hess’s Law Overview Hess’s Law states that the energy change for a reaction depends on the enthalpy of the reactants and products and is independent of the pathway of the reaction. In this experiment you will use calorimetry to measure the heats of reaction for three reactions: Reaction 1 Reaction Equation NaOH(s) → Na+(aq) + OH-(aq) Solid NaOH is dissolved in water 2 Na+(aq) + OH-(aq) + H+(aq) + Cl-(aq) → Na+(aq) + Cl-(aq) + H2O(l) Solutions of NaOH and HCl are mixed 3 NaOH(s)

White Chocolate The history of white chocolate The first chocolate bar was invented in 1847 by the Fry Brothers in Bristol‚ England. White chocolate first appeared in Switzerland in the 1930’s. It was invented by Nestle to use excess cocoa butter. The first bar’s name was called Galak. A year later in the USA‚ white chocolate was first made by the M&M Candy Company. In‚ 1948 introduced by Nestle was the Alpine White chocolate bar containing white chocolate and chopped almonds. In 1993

Experiment 1 Separation of Mixtures Summary of Principles: Most of the materials we encounter in everyday life are not pure substances. Many materials such as sand are formed from physical combination of various substances‚ and are called mixtures. Mixtures can be classified into homogeneous and heterogeneous. The purpose of this lab is to learn how to separate individual components from a mixture through decantation‚ filtration‚ distillation‚ and crystallization. Pre-Lab Questions: Attached

Determination of Heat Capacity In this experiment‚ an improvised calorimeter was used to determine the heat capacity. The calorimeter weighed 4.47 grams prior to the addition of water. Tap water‚ 40 mL to be exact‚ was added to the calorimeter which increased the weight to 43.87 grams. The water was measured using

1. INTRODUCTION A diesel engine is an internal combustion engine that uses the heat of compression to initiate ignition to burn the fuel‚ which is injected into the combustion chamber during the final stage of compression. Diesel engines have wide range of utilization for automobiles‚ locomotives & marines and co-generation systems. However‚ large problem is still related to undesirable emission. The six-stroke engine is a type of internal combustion engine based on the four-stroke
