Worked solutions to student book questions Chapter 2 Analysis by mass Q1. a b Why was the soup sample in Worked Example 2.1 heated to 110°C? Why was it necessary to weigh the sample four times? A1. a b The soup was heated above 100°C to evaporate water from the sample. By repeatedly heating the sample until the mass remained unchanged‚ the analyst could be sure that all the water had been removed. Q2. Some laboratories use microwave ovens in place of conventional ovens to

Chapter 1 Study of Chemistry -Chemistry is the study of matter and the changes it undergoes. It is a very practical science which means that it can be used to determine stuff we do in real life. For example‚ drugs‚ food‚ etc. are made by researching the chemical properties of the substance. -Matter is anything that has a mass and takes up space -Elements are the most basic substances something can be broken down into. There are about 100 elements known to scientists right now. There may be
