Chemistry: How to balance equations with polyatomic ions, examples and step by step solutions, Three helpful tips and tricks that make Balancing Chemical Equations easier, How to balance chemical equations with polyatomic ions by rewriting H2O as H(OH)
Chemical equations usually do not come already balanced. Making sure they are balanced must be done before the equation can be used in any chemically meaningful way. All chemical calculations you will see in other units must be done with a balanced equation.
Balancing chemical equations can look a bit daunting and it scares a lot of students. But don't be afraid… Below we show you a straightforward method to balance equations that you can rely on every time.
The chemical reality of atoms reacting in ratios of small whole numbers is reflected in the final answer. Another way to look at the coefficients is in terms of moles. We can certainly have 3 ⁄ 2 of a mole of carbon atoms or 3 ⁄ 2 of a mole of carbon dioxide molecules.
A chemical equation shows the chemical formulas of substances that are reacting and the substances that are produced. The number of atoms of the reactants and products need to be balanced.
