Purpose The purpose of this experiment is to determine the rate constants‚ k1‚ for the methyl acetate hydrolysis reaction at 25 °C and 35 °C‚ as well as the overall activation energy of the reaction. Methods Methyl acetate was placed in an HCl solution‚ in which it reacts with water to form acetic acid over time. At each time interval‚ an aliquot of the mixture was removed for titration against NaOH to determine the concentration of the acetic acid produced. From the amount of acetic acid produced

* We should follow the rules so that we can maintain peace and organization within our society‚ economy‚ and even our country. Without rules no one would be able to work together. * Two different kinds of people can be heard to utter that question‚ "Why have rules?" One of them does not believe in rules; the other believes in rules and adds a few more words to the question‚ "Why have rules‚ if you are not going to enforce them?" I would like to examine both sides of this argument. Many people

self-esteem cheat on the tests as soon as it is possible. They just think about the results they can attain as a result of cheating and don’t see anything wrong with their behavior (Ward‚ D. A.1986). In conclusion‚ the wish for high‚ distinguishing scores and the lack of self-respect are the contributing factors to cheating during exams. In the future‚ if the awareness of students about cheating will not be raised‚ our society which is full of workers who know little‚ due to such unethical behaviors

Lab #4: Aqueous Reactions Introduction: In this experiment we studied the two different types of aqueous chemical reactions‚ double replacement and single replacement. In a double replacement reaction one or both of the products is an insoluble ionic compound or otherwise known as a precipitate; or a non-electrolyte; or a gas. In a single replacement reaction there is typically a metal and an ionic compound consisting of a metal cation and a non-meatl anion. Singel replacement ractions occur when

Determination of the Solubility Product Constant of Calcium Hydroxide Introduction The equilibrium constant for the solubility equilibrium between an ionic solid and its ions is called solubility constant [1] ‚ Ksp of the solute. For example‚ the solubility product is defined by MxAy(s) ⇋xM(aq)y++ yA(aq)x- (1) Where M is the metal cation‚ A is the anion‚ x and y are the corresponding charges of the ions. The equilibrium expression is Ksp=[MY+]x[AX-]Y (2)

Differences Between Ionic and Covalent Compounds Abstract In chemistry‚ a compound is a substance formed from two or more elements‚ with a fixed ratio determining the composition. A defining characteristic of a compound is that it has a chemical formula. Formulas describe the ratio of numbers of atoms in a substance. Compounds may have a number of possible phases. For a compound to be a liquid or a gas and still be called a compound‚ atoms from the various elements must be stuck together in

Text and Discourse The nature of text When we think of a text‚ we typically think of a stretch of language complete in itself and of some considerable extent. However‚ there appears to be a problem when we have to define units of language which consist of a single sentence‚ but that fulfill the basic requirement of forming a meaningful whole in their own right. For example: “keep off the grass”. This text is complete in terms of communicative meaning. So‚ if the meaningful of the texts does not
