Introduction to Chemical Reactions and Stoichiometry

Chemical reactions are the core engine of chemistry, governing everything from everyday processes like cooking and cleaning to advanced industrial synthesis. A strong grasp of how substances transform is the essential first step in mastering this science. By the end of this course, you will confidently read, write, classify, and balance chemical equations, enabling you to accurately predict reaction outcomes and calculate the quantitative relationships between reactants and products. What you'll learn: * Understand the fundamental definitions of chemical change, reactants, and products, and the laws governing these transformations. * Master the systematic written techniques for balancing chemical equations to satisfy the law of conservation of mass. * Identify and classify the five main types of chemical reactions, including combination, decomposition, displacement, and redox processes. * Apply stoichiometric principles to calculate mass-mass and mole-mole relationships, determining limiting reactants and theoretical yields. * Practice interpreting energy changes (exothermic and endothermic) associated with common chemical processes. This course begins with core terminology and the structure of equations, progresses through detailed reaction classification, and concludes with practical written exercises focused on balancing and quantitative analysis. This course requires no prior knowledge of chemistry and is designed specifically for absolute beginners seeking a robust foundational understanding.
