Common Mistake in Writing Balanced Equations
Students often forget to balance the number of atoms of each element on both sides of the equation when writing balanced symbol equations for neutralisation reactions.
To fix this, carefully count the number of atoms of each element in the reactants and products, and adjust the coefficients to ensure they are equal on both sides.
