The mass of reactants and products are
SpletUse a balanced equation to calculate masses of reactants or products. 4.5.2.2 Conservation of mass. Recall and use the law of conservation of mass. Explain any observed changes in mass in non-enclosed systems during a chemical reaction and explain them using the particle model. AQA Combined science: Trilogy. 5.3 Quantitative chemistry SpletMass and atoms are conserved in every chemical reaction. Interpret the given equation in terms of relative number of representative particles, numbers of moles, and masses of reactants and products. 2K (s) + 2H20 (l)---> 2KOH (aq) + H2 (g) 2 x 6.02 x 10^23 atoms K + 6.02 x 10^23 atoms H2O ---> 2 x 6.02 x 10^23 atoms KOH + 6.02 x 10^23 atoms H2

SpletThe large numbers in the equation show the ratio in which the substances react and are produced. Masses should be multiplied by these numbers. Relative mass of reactants = …
SpletNext, we have to find the amounts of reactants and/or reaction products. For any balanced chemical equation, we know the stoichiometric coefficients that show the amounts (in moles) of both the reactants and products. Knowing the molecular weight of the compounds involved in the reaction, it is easy to find the mass of these compounds in … SpletChemistry Journal 5.4 Stoichiometry Driving Question: How is stoichiometry used to determine the ratio of reactants and products in chemical reactions? Key Ideas and …
