Lab 2 Sara Rodriguez Period 2 Purpose: What is the more accurate way to measure volume‚ by using displacement or by using a ruler? Hypothesis: If the method of displacement is used ‚ then the results will be more accurate than measuring the volume using a ruler. Materials: -250 mL graduated cylinder -Triple beam balance -A weigh boat -Ruler -Samples Procedure: 1. Gather materials such as ‚ samples‚ weigh boat‚ triple beam balance ‚ graduated cylinder‚ ruler and water. 2. Take the materials

Determining the enthalpy of neutralization by calorimetry Anam Iqbal Partner’s name: Danielle Hodgson TA’s name: Karinna Section # 003 Due date: November 24‚ 2009 Introduction The purpose of the experiment is to determine the enthalpy of neutralization reactions by calorimetry. Calorimetry‚ is the science of measuring the amount of heat. All calorimetric techniques are therefore based on the measurement of heat that may be generated (exothermic process) or consumed (endothermic process). The

This experiment will test the suggestion that the enthalpy change between a metal and a solution of a salt is related to the relative position of the two metals in the reactivity. Presumably the further apart in the series the bigger the enthalpy change will be. The experiment is as follows‚ 1) Zn(s) + CuSO4(aq) ZnSO4(aq) + Cu(s) 2) Zn(s) + Pb(NO3)2(aq) Zn(NO3)2 (aq) + Pb(s) Both of the solutions will be in 1mol.dm-3 Apparatus: Distilled Water Polystyrene Cup

more revenue than the other because they want to always maximize their revenue as a hotel. There are tools in place to aid in making these tough decisions; a spreadsheet is created with a displacement analysis to ease in this process. Displacement Analysis Spreadsheet Purpose of the Spreadsheet The displacement analysis spreadsheet helps managers see if the hotel’s revenue is being maximized. With this spreadsheet managers can compare the revenue expected by a certain group. By doing this they will

Name the four behavioral reactions to change. Describe the behavioral signs of each reaction‚ and identify an organizational strategy for dealing with each reaction. Change management is a set of processes employed to ensure that significant changes are implemented in a controlled and systematic manner. One of the goals of change management is the alignment of people and culture with strategic shifts in the organization‚ to overcome resistance to change in order to increase engagement and the achievement

Displacement is the state in which you are not where you belong. The time‚ the place or with whom you are can greatly affect how you feel‚ given that humans seem to always lean towards their comfort zone. In The Awakening‚ a novella written by Kate Chopin‚ the protagonist‚ Edna Pontellier‚ is a displaced person in the Creole world. She feels uncomfortable and out-of-place amongst the Creole women on Grand Isle because of their different cultures. Edna also seems to be ahead of her time‚ as she submerges

Changing the Rate of Reaction PART 1: PARTICLE SIZE Question: How does changing the particle size of marble (CaCO3) affect the rate of reaction when it is added to hydrochloric acid (HCl)? Hypothesis: If I change the particle size of marble to test how to change the rate of a chemical reaction‚ than the chemical reaction with the smallest marble particles will produce CO2 the quickest because the larger the surface area‚ the more place the hydrochloric acid will have to collide with the marble
