Catalysts and chemical reaction - catalysts catalysts are substances used to increase or decrease the rate of a chemical reaction a catalyst is a substance which alters the rate of a chemical reaction but is chemically unchanged at the end of the reactionthe word catalysts originally comes from the word catalysis meaning the change in rate of a chemical reaction. To use a balanced chemical reaction to determine molar relationships between the substances in chapter 5, you learned to balance chemical equations by comparing the numbers of each type of atom in the reactants and products the coefficients in front of the chemical formulas represent the numbers. Reaction, the mass of any other substance in the reaction can be calculated calculations in which a known mass are used to find an unknown mass in a chemical reaction are stoichiometry problems.

Stoichiometry expresses the quantitative relationship between reactants and products in a chemical equation stoichiometric coefficients in a balanced equation indicate molar ratios in that reaction stoichiometry allows us to predict certain values, such as the percent yield of a product or the molar mass of a gas. Mass relationship in a chemical reaction essay introduction: the law of conservation of mass dates from antoine lavoisier’s 1789 discovery that mass is neither created nor destroyed in chemical reactions - mass relationship in a chemical reaction essay introduction in other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of. Lab #7 mass relationships in chemical reactions general discussion in general, we say that a reaction will go to completion (be quantitative) if one of the reactants is completely consumed by the reaction.
