If one does occur you will then write the equation that corresponds to the reaction and classify it. Balancing chemical reactions then allows one to determine stoichiometry calculations by understanding the ratio between reactants and/or products. Chemical reactions are described with chemical equations, which symbolically present the starting materials, end products, and sometimes intermediate products and reaction conditions. For example, the food that you eat is broken down by digestive enzymes into tiny pieces that are small enough to travel through your blood stream and enter cells. Chemical reaction rates depend on factors that influence the frequency of collision of reactant molecules. Endothermic processes require an input of energy to proceed and are signified by a positive change in enthalpy. Chemistry Unit 5: Chemical Reactions.
