Observation of Chemical Change Course: General College Chemistry Purpose This experiment examines the reactions of common chemical s contained in consumer products. The purpose is to observe the macroscopic changes that these chemicals undergo. The goals of the experiment observe properties of chemical reactions and to associate chemical properties with household products. Procedure We do not have the ability to see with a naked eye individual atoms and molecules reacting during chemical changes

2014 Lab report #1 on chemical and physical properties/ changes Introduction Summary: The purpose of this experiment is to allow students to understand how to differentiate physical and chemical properties and reactions of matter by observing changes of matters under circumstances. Physical properties are properties of matter that can be observed without changing the composition of the matter‚ including the volume‚ mass‚ color‚ density‚ and shape of it. Chemical properties include the matter’s

Shelby Brown 8/28/10 Physical and chemical changes lab essay Changes in matter occur every day. There are two types of ways matter can be altered; physically and chemically. Physical changes do not change the composition of the matter while chemical changes occur when one or more substances turn into a completely new substance. Physical changes can be seen through an altering of the substances physical property. A substances physical property is observed and measured without changing
