Easy Steps for Balancing Chemical Equations

Dec 02, 2020· Add Coefficients To Balance Mass in a Chemical Equation . When balancing equations, you never change subscripts.You add coefficients.Coefficients are whole number multipliers. If, for example, you write 2 H 2 O, that means you have 2 times the number of atoms in each water molecule, which would be 4 hydrogen atoms and 2 oxygen atoms. As with subscripts, you don't write
