Stoichiometry and Balanced EquationsCurrent LectureI. Chemical Equationsa. Chemical Equation- symbolic representation of a balanced chemical reactioni. Types of reactions:1. Combination reaction- occur when 2 or more substances (the reactants) react to form one product2. Decomposition reaction- one substance breaking down into 2 or more substances3. Combustion reaction- generally rapid reactions that produce a flame and often involve hydrocarbons reacting with oxygen in the air II. Formula Massa. Molar mass (M)- mass in grams of 1 mole of a substanceThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best usedas a supplement to your own notes, not as a substitute.b. Formula mass (in amu) and molar mass (in grams) are the same i. mass % of Element A = mass of atoms of A/ mass of all the atoms x 100 III. Mole a. Amount of substance that contains many entities i. Avagadro’s number- 6.022 x 10^23 atoms per mole IV. Stoichiometry and Balanced Equations a. Stoichiometry- quantitative study of the reactants/products of a chemical reaction b. How to balance equation — Write all components with states of matter — Start with most complex formula ~ Balance elements that occur in only one other species ~ Continue until all are balanced — Convert coefficients to smallest integer ration — Double check work & verify equal atoms on each
