Name: Julie CanterDate: 1 / 2 1 / 2 4MoleRatiosHow can the coefficients in a chemical equationWhybe interpreted??A balanced chemical equation can tell us the number of reactant and productparticles (ions, atoms, molecules or formula units) that are necessary toconserve mass during a chemical reaction. Typically when we balance thechemical equation we think in terms of individual particles. However, in reallife the reaction represented by an equation occurs an unimaginable numberof times. Short of writing very large numbers (1022or larger) in front of eachchemical in the equation, howTcan we interpret chemical equations so thatthey more realistically represent what is happening in real life? In this activityyou will explore the different ways a chemical reaction can be interpreted.Model1 - A C h e m i c a l ReactionN2(g)+3H2(g) -. ,.2NH iq) ,1. Consider the reaction in Model 1.d.
