in heat‚ Q‚ given by an exothermic reaction or the heat absorbed by an endothermic reaction. To do this‚ we use the concept of calorimetry‚ the measuring of heat of chemical reactions or physical changes. For this concept‚ we use a device called a calorimeter‚ which is a device that creates an isolated system that enables the user to accurately measure the change in temperature‚ ΔT. We use the following formula in order to calculate Q‚ quantity of heat‚ given the mass of the substance‚ m; its specific

Heat of Neutralization: Lab Report In part A of this lab I determined the heat capacity of a calorimeter made out of two Styrofoam cups nesting together with a cardboard top containing a hole in the middle. First I placed 50 mL of water in the calorimeter‚ waited five minutes for the water to reach equilibrium‚ and used the computer’s temperature instrument to record the final temperature of the system. Next I heated 50 mL of water in a 250 mL beaker until the water reached 43.1 C (approximately

Enthalpy of Neutralization Introduction Energy changes always accompany chemical reactions. If energy‚ in the form of heat‚ is liberated the reaction is exothermic and if energy is absorbed the reaction is endothermic. Thermochemistry is concerned with the measurement of the amount of heat evolved or absorbed. The heat (or enthalpy) of neutralization (∆H) is the heat evolved when an acid and a base react to form a salt plus water. Eq. 1 HNO2(aq) + NAOH(aq) → NaNO2(aq) + H2O(l) + Q Q in the

___________________ Date ___________________ NEUTRALIZATION TITRATIONS INTRODUCTION The neutralization of hydronium or hydroxide ion to form water is widely used as the basis for volumetric determinations of acids‚ bases and salts of weak acids. The reaction is characterized by a rapid change in pH near the equivalence point‚ a change that is readily detected by an acid-base indicator or that can be followed electrically by use of a pH meter. Neutralization titrations are performed with standard

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

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

Walker writes based off her life experience‚ African American women‚ her mother’s teachings‚ and family traditions. Her writings‚ Everyday Use and The Color Purple are two of her most popular writings. Both writings highly reflect all of those characteristics in both good and bad ways. Many people have reviewed her work‚ and she has mostly positive feedback. Everyday Use was written in 1973. It is a story about a family of three African American

“Everyday Use”‚ by Alice Walker‚ and “Everything That Rises Must Converge”‚ by Flannery O’Connor are two stories which both incorporate important themes about family history and how that history contributes to a person’s identity. “Everyday Use” shows how family history defines us and “Everything That Rises Must Converge” represents how family can reinforce the belief in our identities and views of self worth. There are undeniable similarities between both of the stories in how family is viewed

In Alice Walker’s short story Everyday Use‚ she bring up many issue such as comparing relationship between heritage and tradition past. The story also question whether or heritage is something one use or something one possess. To understand heritage‚ one must have a personal connection of that history‚ in everyday use Dee do not really have a connection to her heritage so blind by anger of what she does not understand she view her heritage in history as an oppression.
