Pentane‚ Propane-1-ol and Propane-2-ol would be the most appropriate to take on a camping trip to a national park where wood cannot be used to burn. Factors that need to be considered are: • Heat of combustion (flash point) • Heat of vaporisation (boiling point) • How long the fuel will last • Does the fuel heat up the water relatively quickly • Does the fuel combust completely Hypothesis: If the tests are all successful‚ Pentane should produce a larger flame than the Propan-1-ol or Propan-2-ol as

EXPERIMENT 4B: THE MENDELEEV LAB OF 1869 Materials: 30 element cards‚ periodic table Aim: How can we identify elements based on their propeties? Background: Russian chemist Dmitri Mendeleev is generally credited as being the first chemist to observe patterns emerge when the elements are arranged according to their properties. Mendeleev’s arrangement of the elements was unique because he left blank spaces for elements that he claimed were undiscovered as of 1869. Mendeleev was so confident

Aim To investigate the effect of molar mass on the molar heat of combustion of adjacent members of a homologous alcohol series. Introduction Chemists refer to the energy stored in a substance as the heat content or enthalpy of the substance. The heat of reaction is determined by the difference in the enthalpy between the reactants and products. The molar heat of combustion of a substance is the quantity of heat liberated when one mole of that substance is burnt completely in air. In the case

Formal Lab Report #1 I. Basics Title of the Experiment: The Empirical Formula of an Oxide Authors: Section Number: Chemistry Location and Date II. Abstract The aim in this lab was to determine the empirical formula of an oxide of magnesium through combustion in air. This was achieved by heating an established mass of magnesium in air inside of a crucible‚ ultimately attaining a compound that contained Mg and O. The major result of the experiment was the empirical formula of the oxide of magnesium

October 1‚ 2013 Chemical Reactions of Copper Objective The objective of this lab is to convert copper (Cu0) “in a series of reactions to various compound containing copper as the Cu2+ species” (CHM111 Laboratory Manual) in order to prove the Law of the Conservation of Mass. Introduction In this experiment‚ we took a look at how copper (Cu0) reacts with different substances to get an end result where it is transformed back to its original state. There were five different reactions that involved

7/21/2013 | | This experiment is to calibrate a constant pressure calorimeter to experimentally determine a series of heats of reaction that will be used to predict the enthalpy of reaction for another reaction using Hess’ Law and to determine heats of dissolution for a number of ionic salts that will be used to predict lattice energy again by using Hess’ Law. Heat may increase during experiment and undergo exothermic reaction. Analysis: Q = m c (Tf - Ti) = 27.9°C – 21.3°C = 6.6°C Q =
