Experiment 7: A Study of Chemical Changes: Types of Chemical Reaction INTRODUCTION Chemical changes are results of chemical reactions. All chemical reactions involve a change in substance and a change in energy. They are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products. There are different types of chemical reaction classified into 4 general types‚ namely‚ Synthesis‚ Decomposition

Experiment In this lab we were asked to observe changes and colors when mixing two or three chemicals together. The actual experiment itself used twelve different pipits and three chemicals I selected from my house. To begin‚ I first gathered everything‚ including the 96 well plate‚ 24 well plate‚ goggles‚ and gloves along with the observations of chemical changes bag. I set it up all on the the kitchen table that had paper towels on it. Next‚ I made my data table so that I could record my reactions

Naming Chemical Compounds General Information: Scientists all around the globe use a standard method for naming chemical compounds. The standards were set up by an international committee sponsored by the International Union of Pure and Applied Chemistry (IUPAC). Having this standard makes life easier for people who use these compounds everyday. It would be tough to set up any experiment if scientists everywhere used different names for the same compound. It would also make the lab a

eight types of chemical reactions. These eight reactions are Decomposition‚ Composition‚ Acid/Base‚ Synthesis‚ Single-Replacement‚ Double-Replacement‚ Precipitation‚ and Redox. Though these eight could be referred to as the same due to them being chemical reactions. They are actually very different. An example of this difference is Decomposition and Synthesis. Decomposition is when a compound is broken into smaller chemical species while a Synthesis reaction is two or more chemical species combining
