Enthalpy of Neutralization Introduction: The purpose of this lab experiment was to determine the molar concentration of the unknown HCl by using a coffee cup calorimeter. A coffee cup calorimeter is made of Styrofoam cups with a thermometer that is placed from the top and into the calorimeter to measure the temperature as the reaction happens. The Styrofoam cup used for the calorimeter creates an isolated system as it acts as a heat insulator between the cup and the surrounding. When a reaction happens

Abstract: This project looks at how the temperature of an experiment can affect its reaction time. The purpose of this experiment is to determine if dissolving reactions are affected by waters temperature. I believe that if the H2O temperature increases‚ then the Alka-Seltzer tablet will dissolve faster because the hot water molecules will move faster colliding with the tablet particles. Water will be the independent variable due to the fact is will always stay in its same form throughout the

Heat‚ Temperature‚ and Phase Changes Assessment Practice Answer This graph shows what happens to the temperature of the water‚ while it was boiling in a kettle‚ as heat energy was being added to it and what the water was doing will it began to warm and change states. During a phase change‚ the temperature remains mainly constant. This occurs because the heat energy is used to break the bonds between the ice molecules as they turn into a liquid phase. It is possible to constantly

Sykes and Matza techniques of the neutralization theory explains the motives that hackers use when committing a cybercrime. The theory is said to be that hackers are deviant‚ this way they feel no guilt towards their victims. The five neutralizations explain concerning this theory rely on the thoughts of the hackers. The first one being in denial of responsibility‚ this gives the hacker the opportunity to justify their actions. When doing so they often blame their criminal acts on a force that is

Gender neutralization. Is the premise outlined in “X” and currently happening to Storm wrong or right? There are a lot of problems arouse on the issue of Gender neutralization. People start commenting about it‚ they blog‚ post videos on Youtube etc. They all answered the question if gender neutralization is either right or wrong and if it’s appropriate to early new bourns? In the case of the Canadian Parents raising gender-neutral babies by not revealing the sex of their baby to anyone

Skyes and Matza’s theory on the techniques of neutralization was originally channeled towards juvenile delinquency but is also very effective for understanding how police officers excuse‚ justify‚ and rationalize unethical behaviors. Techniques of neutralization are used to maintain a positive self-image: denial of responsibility‚ denial of injury‚ denial of the victim‚ condemnation of condemners‚ and appeals to higher loyalties. Denial of responsibility provides police with a justification for

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

NEUTRALIZATION TEST FOR VIRUS Neutralization of a virus is defined as the loss of infectivity through reaction of the virus with specific antibody. Virus and serum are mixed under appropriate condition and then inoculated into cell culture‚ eggs or animals. The presence of unneutralized virus may be detected by reactions such as CPE‚ haemadsorption/haemagglutination‚ plaque formation‚ disease in animals. The loss of infectivity is bought about by interference by the bound Ab with any one of the

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

of temperature change will result from heating ice to liquid‚ then boil (steam)? What will happen to the water after the boil? I hypothesise the water heats ice to liquid and then goes to simmer and boil. The independent variable is the hot plate changed to a burner itself. The dependent variable is what we are measuring is the time. The steps in the lab were to first start off with a burner‚ ice and water in a beaker‚ then record time and water temperature. Also‚ some phase changes in between
