batch reactor to study reaction kinetics under ideal conditions. This experiment was carried out in other to study effect of temperature on reaction rate constant and also to study the effect of the reaction rate constant in a batch stirred tank reactor its important in chemical industry because it is used to determine the effect of temperature on reaction rate constant; it is also used in chemical and process industry for solids dissolution‚ product mixing‚ chemical reaction‚ batch distillation‚ crystallization

2- Three experimental methods that student could use to determine whether the unknown substance is ionic or covalent are as follows: a) Heath stability experiment: as we learned in experiment 2‚ Ionic substances have high heat stability. When we heated them over Bunsen burner they always left residue. However‚ covalent substances have low heat stability and don’t leave residue. b) Ionic compounds are good electrolytes while covalent substances are either not an electrolytes or a very weak one. c)

Factors Influencing Rate of Reaction Aim To investigate several effects believed to influence rate of reaction‚ concentration of a substance and temperature‚ and observe the effects. Hypothesis Concentration and temperature will both increase the rate of reaction in accordance with collision theory. Introduction The reaction rate or rate of reaction for a reactant or product in any given reaction can be defined as the speed with which a reaction occurs. For example‚ the oxidation of iron

The essay “Caught in the net” written by Eva Tihanyi is an essay describing internet users. The thesis in Eva’s essay is “For some‚ the Net is a reliable companion‚ twenty-four hours a day‚ seven days a week—one that never sleeps. For others‚ it simply provides easy access to a vast array of data”. There are certain people that use the internet as a education tool and a way to stay connect to the world; but there is also people who abuse it and take advantage of the internet which in turn takes

Chemical Reactions The idea of chemical reactions was investigated about two hundred and fifty years ago‚ when a man named Antoine Laurent Lavoisier wanted to know about the importance of chemical changes. Also‚ in the 19th century‚ John Dalton made the atomic theory. Dalton said that bonding atoms together makes new substances‚ which is a chemical reaction (History of chemical reactions). The definition of chemical reaction is‚ “the processes in which substances undergo chemical changes‚ which

Experiment 1: Observations of Chemical Changes Abstract: In the lab 1 experiment‚ the objective was to observed properties of various chemical reactions between twelve different basic compounds. Each reaction revealed chemical properties consisting of color change‚ CO2 gas formation‚ and/or precipitate formation. Certain reactions made it possible to distinguish between an acid and a base. Through the results of this experiment‚ chemical properties observed in the reactions could be used to associate
