What are the 3 rules for balancing equations?

Summary

• To be useful, chemical equations must always be balanced. Balanced chemical equations have the same number and type of each atom on both sides of the equation.
• The coefficients in a balanced equation must be the simplest whole number ratio. Mass is always conserved in chemical reactions.

How do you balance equations quickly?

Write down how many atoms of each element there are on each side of the reaction arrow. Add coefficients (the numbers in front of the formulas) so the number of atoms of each element is the same on both sides of the equation. It’s easiest to balance the hydrogen and oxygen atoms last.

Which is more efficient to balance chemical equations?

Thus, the balanced chemical equation is obtained. The algebraic method of balancing chemical equations is considered to be more efficient than the traditional method. However, it can yield fractional values for the stoichiometric coefficients, which must then be converted into integers.
