Draw / write: Complete the following table with the correct names for the compounds.
Name one type of chemical reaction.
Be able to write word equations for chemical reactions where compounds are made or broken down.
Chemical word equations are written descriptions of chemical reactions. Each equation must include the reactants (starting substances) and products (resulting substances). These are written like equations in maths but instead of an =, we use an arrow.
Writing Chemical Word Equations
Word Equations are a way of showing a chemical reaction using words and symbols to represent elements and molecules. Reactants are the substances that are involved in the chemical reaction. Products are the substances that are formed as the result of the chemical reaction.
