If there are no inequalities, the chemical equation is said to be balanced. In this lesson we look at the balancing of chemical equations and why it is important. We also learnt how to balance the equations.

Acids, bases and pH values
Solutions are classified as acidic or basic based on their hydrogen ion concentration relative to pure water and the pH scale is used to rank solutions in terms of acidity or basicity (alkalinity). In this lesson we investigate acids and bases and the differences between them. We also look at th...

Reactions of metals with oxygen
When a metal reacts with oxygen, a metal oxide forms. The general equation for this reaction is: metal + oxygen → metal oxide. In this lesson we take a look at the reactions that take place between metals and oxygen and the products that form when these types of reactions take place.

Reactions of non-metals with oxygen
Non metals reacts with oxygen to form oxides. We take a look at the different reactions between non-metals and oxygen and the products that form during these types of reactions.
