Chemistry Chapter 9: Introducing The Basic Elements And Reactions

Chemistry Chapter 9: Introducing The Basic Elements And ReactionsStarting with Chemistry chapter 9 will help students learn the basic elements and reactions that occur in the different reactions within chemical processes. This will give them a general understanding of chemistry as well as the importance of using scientific principles to make informed decisions. They will also be able to use their common sense when dealing with chemical reaction to solve common problems.The chapter contains lists for two of the most important chemical terms to memorize at an elementary level - the element and the reactants. These will have special applications for a greater understanding of the material.Using the list of reactants and the list of the elements is one way to remember these elements and their reactions. Each reaction requires a specific type of element or group of elements to react with, thus it is important to memorize the list. Other reaction names include: the individual elements, che mical compounds, oxides, neutral compounds, and dichromates. Students should learn the symbols for these different types of reactions.In addition to learning the symbols for the elements, the chapter teaches students to understand what the word 'compound' means and how this is used when referring to the substances they are made from. A compound is made up of two or more elements. There are some chemicals that are comprised of compounds consisting of two or more individual chemical elements.When learning about chemistry, it is important to understand how different reactions can be used to produce different products. One product created by an oxidizing reaction is shown with the 'X' symbol. The symbol for a reducing reaction is shown with the 'R' symbol.Oxidation can create a compound which can only be obtained from an oxidation reaction. An oxidation reaction will only occur when an element has already been changed to another element. The reaction which creates a molecule containing oxygen can take place with carbon dioxide and water, or with nitrogen, potassium, and sodium.With the right knowledge of chemistry, students will be able to recognize properties of different substances and elements which can be used to assist them in making and buying chemical products. Chemical reactions in the chemistry section of the grade school curriculum will help students in identifying different chemical reactions and how chemical products and reactions can create useful products.
