A word equation represents a chemical reaction using the names of the substances involved. Word equations do not show any chemical symbols or formulae.
Reactants are substances that react together in a chemical reaction. In a chemical reaction, the atoms or ions in reactants separate from one another. They join back together in a different way to form products.
Word equations always take this form:
reactants → products
A + sign separates two or more reactants, or two or more products.
Potassium hydroxide reacts with sulfuric acid. Potassium sulfate and water are formed in the reaction. This means that:
There can be different numbers of reactants and products. For example:
Nitrogen and hydrogen react together to form ammonia. Give the word equation for the reaction.
nitrogen + hydrogen → ammonia
