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

Design an experiment to investigate the stoichiometric mole ratio of a chemical reaction. Present your data in terms of the mass of one reactant compared to the mass of one product. Purpose: The experiment will be designed to find out the stoichiometric mole ratio of Barium Chloride and Silver Nitrate yielding a precipitate of Silver Chloride in a Barium Nitrate solution. (BaCl2 + 2AgNO3 -> Ba(NO3)2 + 2AgCl) Research Question: How will the amount of Barium Chloride and Silver Nitrate

Strike in Space Case Study Executive Summary This case centers on the original 3 Skylab missions that began in 1973 following a successful series of Apollo missions starting in the 1960’s. NASA viewed the Skylab missions as logical successors of the Apollo missions and each of the Skylab missions picked up where the prior one left off. The primary focus of the missions was to determine if humans could in fact live comfortably for extended periods of time in weightless conditions and prior to
