Lab report for chemestry

Abstract . The laboratory work performed was undertaken to explore the multiplicity and possibilities of chemical reactions . During the course of the work , combination , decomposition , single and double displacement and rearrangement reactions were performed

Mixed type reactions of different types were also performed

Qualitative signs and evidences of chemical reactions that take place in the mixture of reactants , were examined during the course of the work Different types of reactions regarding change of energy were studied

As a result of laboratory work , skills for performing basic types of chemical reactions and using

simple chemical accessories and glassware were obtained

Introduction . Chemical reaction - an interaction between substances that results in formation of new substances that were not in the mixture initially , or in change of existing substances

Reactant - a starting substance that enters chemical reaction

Product - a final substance that is formed during the reaction

Catalyst - a substance that facilitates a chemical reaction without being consumed itself

Combination - a reaction that results in formation of a composite product from more simple reagents

Decomposition - a reaction that results in disintegration of a composite reagent onto more simple products

Displacement - a reaction that is results in substitution of a chemical group of a composite reagent by another chemical group

Rearrangement - a reaction that changes of atoms in a reactant without changing the set of the atoms in that reactant

Exothermic - a reaction that is accompanied with emission of energy

Endothermic - a reaction that is accompanied with absorption of energy
