Word equations use words to indicate reactants and products of chemical reactions.

Word equations in chemistry are used to describe chemical reactions. They show the names of the reactant(s) on the left side and the product(s) on the right side. The reactants and products are separated by an arrow (→) which signifies the direction of the reaction. For example, in the reaction of hydrogen with oxygen to produce water, the word equation would be: Hydrogen + Oxygen → Water.

Here are the steps to write a word equation:

1. Identify the reactants: These are the substances that react with each other in the chemical reaction. They are usually written on the left side of the equation.

2. Identify the products: These are the new substances that are formed as a result of the chemical reaction. They are usually written on the right side of the equation.

3. Write the word equation: Write the names of the reactants, followed by an arrow, followed by the names of the products.

4. Check the equation: Make sure that the equation accurately represents the chemical reaction. If necessary, adjust the amounts of reactants and products to reflect the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.
