Step 4: Substitute Coefficients and Verify Result. Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. Since there is an equal number of each element in the reactants and products of Na2SO4 + BaCl2 = BaSO4 + 2NaCl, the equation is balancedStep 4: Substitute Coefficients and Verify Result. Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. Na2S2O3 + 3 H2So4 = Na2So4 + 4 So2 + 2 S + 3 H2O. Reactants. Balanced chemical equation - A chemical equation in which the number of each type of atom is equal on the two sides of the equation. Subscripts - Part of the chemical formulas of the reactants and products that indicate the number of atoms of the preceding element.
Step 4: Substitute Coefficients and Verify Result. Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. Na2CO3 + 2 HNO3 = Na2(NO3)2 + H2CO3. Reactants.
Step 4: Substitute Coefficients and Verify Result. Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. 2 NO3 + H2SO4 = 2 HNO3 + SO4. Reactants. Products. NVPwT.
