The Periodic Table of Elements 01
WHAT ARE CHEMICAL REACTIONS? A chemical reaction is a process where one or more substances ( reactants ) change into one or more new substances ( products ). A + B A B
WHAT IS REACTANTS AND PRODUCTS? Forms as a result of reaction Starts a chemical reaction REACTANTS PRODUCTS
WHAT IS A CHEMICAL EQUATION? A chemical equation shows the starting compound— the reactants —on the left and the final compound—the products —on the right, separated by an arrow.
EXAMPLES OF BIOCHEMICAL REACTIONS
TYPES OF REACTIONS 1. C omposition/Synthesis Reactions 2. Decompositions Reactions 3. Displacement Reactions 4. Reduction- Oxidation (Red- Ox) Reaction
Composition/Synthesis Reactions These are reactions where multiple reactants, such as element A and B interact with each other to form element a single product, compound AB. Energy is required for composition reactions to occur. The general formula for composition reactions is: A + B = AB.
Decomposition Reactions These are reactions where one (1) compound undergoes changes due to an external factor that initiates the reaction (temperature, Ph ). It is broken down into its constituents and releases energy as the bonds are broken.
Displacement Reactions These are reactions where one (1) compound undergoes changes due to an external factor that initiates the reaction (temperature, Ph ). It is broken down into its constituents and releases energy as the bonds are broken.
Reduction-Oxidation (Red-Ox) Reactions Oxidation–reduction reactions, commonly known as redox reactions, are reactions that involve the transfer of electrons from one species to another. The species that loses electrons is said to be oxidized, while the species that gains electrons is said to be reduced.
