Observing and deciphering Chemical Changes Purpose The purpose of this experiment is to observe reactions of chemicals that can be found in consumer products. Through observation‚ students should be able to interpret the chemical reactions and determine some characteristics‚ such as pH and solubility. Method 1. Pipets containing chemicals will be opened using scissors to snip the end and each pipet will be placed in a well of a 24-well plate. The scissors must be washed between each pipet. 2

Class X Question 1: Chapter 1 – Chemical Reactions and Equations Science Why should a magnesium ribbon be cleaned before burning in air? Answer Magnesium is very reactive metal. When stored it reacts with oxygen to form a layer magnesium oxide on its surface. This layer of magnesium oxide is quite stable and prevents further reaction of magnesium with oxygen. The magnesium ribbon is cleaned by sand paper to remove this layer so that the underlying metal can be exposed into air. Question
