EXPERIMENT 1: CHEMICAL REACTIONS
I. INTRODUCTION – OBJECTIVES
In this first experiment, we will perform 8 chemical reactions and 1 flame test in order to determine 2 things :
a) firstly, we can know whether a reaction occurred or not. To complete our mission, we need to observe carefully some signs of chemical reaction’s appearance such as the change in color of solution, precipitate’s existence, the release of gas, also check the change of heat and light.
b) secondly, we need to have knowledge about 5 types of reactions and then put experiments below into practice classify type of each reaction. Furthermore, we also learn how to describe chemical changes carefully, beside that we will practice again writing and balancing chemical equations skills.
