Boiling Point Elevation 4-4 Boiling Point Elevation If you dissolve a substance such as ordinary table salt (NaCl) in water‚ the boiling point of the water will increase relative to the boiling point of the pure water. In this assignment‚ you will dissolve a sample of NaCl in water and then measure the boiling point elevation for the solution. 1. Start Virtual ChemLab and select Boiling Point Elevation from the list of assignments. The lab will open in the Calorimetry laboratory with a calorimeter

Linear Programming Model in Operation Research study is usually mathematical type of model which contains set of equations that represent objective function and constraints. The keywords in this article are Objective Function and Constraints‚ according to Heizer & Render (2008) Objective Function are mathematical expression expressed in linear programming designed to maximizes or minimizes some quantity‚ for example profit can maximized while the cost might be reduced. The objective function is also

Unit 4 Assignment 4.3 Implementation of a Data Classification Policy Risk Assessment One the first steps in implementing an effective security plan is to periodically assess Organizational risks. Identifying and mitigating risk will help in establishing a security management structure and assigning security responsibilities. Without having an understanding of your risk you are unable to determine the proper security policies‚ procedures‚ guidelines‚ and standards to put in place to ensure adequate

Problem Statement: Some families didn’t want to travel overland to California so they took ships around Cape Horn at the tip of South America. Say a ship leaves San Francisco for New York the first of every month at noon. At the same time a ship leaves New York for san Francisco. Every ship arrives exactly 6 months after it leaves. If you were going to San Francisco from New York How many ships from San Francisco would you meet? I assumed that entering and exiting the harbor does not count

Linear Kinematics. Fielding a backhand requires acceleration and deceleration. The fielder must accelerate towards the ball and decelerate when approaching the ball to field it. Acceleration occurs in the first three phases of the backhand and deceleration occurs in the critical phase‚ drive phase‚ when the fielder picks up the ball with their glove. Acceleration helps the athlete gain distance between the fielding positon and the ball. This allows the fielder to get their glove in front of the

Question 1 1. Rockhampton City Council wished to investigate the effect of household income and household size on water consumption. From a survey of 315 households‚ the following relationship between weekly water consumption in litres‚ weekly household income measured in dollars and the number of members of the household was estimated: WATER = 86.64 + 0.3685*INCOME + 358.5*SIZE Holding weekly income constant‚ by how much does water consumption (measured in litres) increase if a household gains

The article “The British PoW who broke into Auschwitz – and survived” by Jake Wallis Simons‚ in my opinion‚ was underwhelming and did not quite do justice to the actions taken by Denis Avery. The issue I had with the article was the lack of detail in various parts of the story. For example‚ while Simons goes into extensive detail about Avery’s personality and actions to get into Auschwitz‚ he glosses over other parts‚ like the information that Avery received in the camp. Only a couple short paragraphs
