Determination of Chemical Formulae: The Reaction of Zinc and Iodine By Sarah Abstract: The main objective of this experiment was to use to the reaction between zinc and iodine to examine the validity of the Law of Conservation of Mass and the Law of Constant Composition. The Law of Constant Composition was tested by determining the mass of each of the reactants‚ zinc and iodine‚ and comparing their total to the mass of the zinc iodide product plus the excess zinc. The total mass of the reactants

Physics 211 Experiment 1: Free Fall - Determining the acceleration of gravity Prior to Lab: Derive the numbered equations (Equations 1‚ 2 and 3) in the lab instructions using the definitions of velocity and acceleration (a=dv/dt and v=dy/dt). Object: The object of this experiment is to determine the value of the acceleration of gravity by measuring the rate of acceleration of a freely falling object. In addition‚ one will be able to compare theory with experiment for constantly accelerated

and gravity can negatively influence the playability of sports‚ however alterations can be made so that this hobby can continue to the stars. There are forces that are constantly being exerted on a soccer ball in flight. Forces are vital components as they provide the ball the ability to travel through the air. The forces exerted on a soccer ball include the air resistance‚ weight as well as lift (depicted on Figure 1) – which are all dependant of the gravity and air conditions. If the gravity and

Melting pointe determination #01 Introduction: Objective To learn how to obtain an accurate melting point using a MELTING POINT APPARATUS‚ then use them to draw eutectic curve and determine the eutectic point. Melting point of a solid is the temperature at which the solid and its liquid form are in equilibrium‚ i.e.‚ molecules move back and forth between the two states at the same rate‚ so both phases remain present. If the temperature of a solid is measured carefully as the solid is heated
