A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products.In other words, the mass and the charge are balanced on both sides of the reaction. Also Known As: Balancing the equation, balancing the reaction, conservation of charge and mass.
Sep 18, 2019· From the balanced chemical equation, use a mole ratio to calculate the number of moles of gold that can be obtained from the reaction. To calculate the mass of gold recovered, multiply the number of moles of gold by its molar mass. Solution: A The equation is balanced as written; proceed to the stoichiometric calculation. Figure (PageIndex{2 ...
