Experiment 12: Calorimetry and Hess’s Law Purpose: The purpose of this lab is to determine the enthalpy of reaction for the burning of one mole of magnesium in oxygen. Although the reaction is exothermic‚ the ∆HRXN will be determined by using calorimetry and then using Hess’s Law to manipulate the data collected to yield the answer needed. Procedures: Dillon‚ Stephanie. “ Calorimetry and Hess’s Law.” Laboratory Manual. Pearson Publishing‚ 2012‚ pp.168-177. Data and Results Part A

Activity 1 1. Describe two variables that affect the rate of diffusion. a. There are alot of different variables or factors that can affect the rate of diffusion‚ for example: size of the molecule‚ shape of the molecule‚ concentration gradient‚ charge of the ions‚ temperature‚ environment‚ etc. The rate of the diffusion can increase as diffusion distance increases‚ concentration gradient increases‚ surface area increases‚ temperature increases‚ and many more. 2. Why do you think the urea was not

The Smallest Particle? The Atom. Adapted from “Newton Typepad“ website‚ 2008‚ http://newton.typepad.com/content/2008/07/atom-powered-co.html As far back‚ from my school years‚ as I can remember the word atom signified the smallest particle of matter. This is a very layman like attitude a scientist would abhor‚ because a scientist knows that this concept of ‘the smallest particle of matter ’ has been changing rapidly over the years. The Greeks‚ it is said‚ coined the word “atom”. When this concept
