History of C+ The creation of C++ was first put into motion in 1979 by its creator Bjarne Stroustrup. Bjarne was working on his PhD thesis at Cambridge University. He was using a large and detailed simulator‚ that he had written in Simula‚ to simulate running software over a network of computers. He found programming in Simula enjoyable and was impressed by how the programs class structure helped him organize his code. As the size of his program increased‚ he found that the language became increasingly

Salt from green beans Name: Ashni Couprie and Dennise Susanto Class: 5c Introduction From previous experiments we ’ve learned that salt is extracted from green beans. To be more specific: salt is extracted from when the beans are cooked in water in which salt has been dissolved. This experiment is based upon the osmoses theory. According to this theory the cell walls of the green beans are what we call a semi permeable membrane. This membrane only lets water through and not the substance

The milgram experiment. The three people involved were: the one running the experiment‚ the subject of the experiment a volunteer‚ and a person pretending to be a volunteer. These three persons fill three distinct roles: the Experimenter an authoritative role‚ the Teacher a role intended to obey the orders of the Experimenter‚ and the Learner the recipient of stimulus from the Teacher. The subject and the actor both drew slips of paper to determine their roles‚ but unknown to the subject‚ both slips

Experiment 3 Objectives Separation by Solvent Extraction To separate a mixture consisting of a carboxylic acid and a neutral compound by using solvent extraction techniques. Introduction Frequently‚ organic chemists must separate an organic compound from a mixture of compounds‚ often derived from natural sources or products of synthetic reactions. One technique used to separate the mixture compounds is called extraction. Extraction is a process

Calorimetry Experiment Purpose: The objective of this lab is to determine the enthalpy change for NaOH(aq) + HCl(aq) NaCl (aq) + H2O(l) Procedure: Before measuring the enthalpy of acid base neutralization‚ my partner Brian and I determined a calorimeter constant‚ using a homemade polystyrene calorimeter. With the following formula and data: qhot= cm (Tf-Ti) qcold=cm(Tf-Ti) SYSTEM DATA SURROUNDINGS DATA Water cold Mass: 50mL Water hot Mass: 50mL C=4.18 C=4.18 Ti=20 C Ti=31 C Tf=31

perform the experiment‚ first the calorimeter was filled with 100 mL of water using a graduated cylinder‚ and the temperature of the water was found and recorded. Next‚ the beaker was filled 3/4 full with water and placed on the stand of the ringstand above a gently burning flame from the Bunsen Burner. Then‚ the mass of the test tube and wax was found and recorded‚ and the tube was placed in the beaker. After the wax in the tube melted‚ the tube was placed in the calorimeter‚ using a wire gauze
