Measuring the enthalpy change of vaporisation of water You should attempt this part of the activity even if you have not seen the demonstration of the practical. 1. Calculate a value for ∆Hvap for water in KJ mol-1 using the data from the demonstration. Also‚ calculate ∆Hvap from the following data gathered by a student; 8100 J were needed to distil 2.95g of water. a) Explain why the boiling tube was surrounded with expanded polystyrene (or other similar insulation)‚ but the condenser was left

From the experimental data and through its analysis‚ the enthalpy of combustion for the five alcohols were determined; methanol‚ ethanol‚ propanol‚ butanol‚ and pentanol. As the line of best fit in the graph suggests‚ the enthalpy of combustion increased as the sizes of the molecules increased. This was predicted in the hypothesis and proves it to be correct. As seen on the graph‚ the enthalpy of combustion increases from 140kJ/mol for methanol‚ which has the smallest molecular mass‚ to 530kJ/mol

Classifying Chemical Reactions Purpose: To observe and differentiate between the four different types of chemical reactions. Variables: The independent variables are the sodium chloride‚ sodium carbonate‚ magnesium‚copper‚ copper (11) sulfate‚ silver nitrate‚ oxygen‚ lead(11) nitrate‚ sodium carbonate‚ copper (11) sulfate pentahydrate. The dependent variables are the chemical reactions that are being looked for. For example decomposition‚ synthesis‚ single displacement or double displacement of compounds

which it can leave a mark. The measurement for the vertical displacement‚ the handmade ball catcher is suspended with light string‚ as the collision occur‚ the ball catcher starts to rotate in circular until it reaches the maximum height‚ this can increase or decrease the measurement of height and make it harder to record the precise measurement for vertical displacement. Data Table 1(kinematic experiment). The horizontal displacement of the ball when the mass of the ball‚ angle of release

Using Hooke’s Law‚ apparatus weights and 2 types of spring was computed for the spring constant. By performing more than three trials and increasing the weights 10g per trial‚ the behavior of the spring constant was observed with varying force and displacement. With the spring constant obtained‚ the work done on the spring can also be calculated. II. Introduction The experiment defines elasticity which is the ability of an object to return to its original length and shape after the deforming forces

The Agony of Displacement in "Mrs. Sen’s" The word diaspora (originally the dispersion of Jews outside of Israel from the sixth century b.c.‚ when they were exiled to Babylonia‚ until the present time) refers to the movement of the population from its original homeland. For James Clifford‚ it involves dwelling‚ maintaining communities‚ having collective homes away from home. In order to provide a “defining" model‚ Clifford turns to William Safran’s definition of Diaspora: "expatriate minority communities

Vapor Pressure and Enthalpy of Vaporization of Water 1/9/12 Emily Toy Lab Partner: Zack Ronnei Instructor: Ms. Olsen‚ AP Chemistry Purpose: The purpose of this lab is to find the vapor pressure of water at temperatures between 50oC and 80oC. Procedure: 1. Take a10 mL graduated cylinder and fill it with 7 mL of water. 2. Next fill a 1000 mL beaker ¾ full with water. 3. Cover the graduated cylinder by putting your finger on top and place the cylinder in the 1000 mL beaker. Make

Heredity determines personality Argument supporting Heredity determines personality Introduciton: Personality is defined as the sum total of beliefs‚ behaviors‚ attitudes andvalues that distinguishes an individual. Each of us has unique personalitieswhich distinguish us from the others. Even twins who look alike and arereared in the same environment differ in personalities. A number of factorsdetermine a person’s personality. These include environment and genetics.Our personality is the product
