Document Summary
Some reactions go to completion, where the reactants are used up to form the product molecules and the reaction stops when all of the reactants are used up. In reversible reactions, the product molecules can themselves react with each other or decompose and form the reactant molecules again. It is said that the reaction can occur in both directions: the forward reaction (which forms the products) and the reverse direction (which forms the reactants. When writing chemical equations for reversible reactions, two arrows are used to indicate the forward and reverse reactions. Each one is drawn with just half an arrowhead the top one points to the right, and the bottom one points to the left. The reaction for the haber process which is the production of ammonia from hydrogen and nitrogen: Hydrated salts are salts that contain water of crystallisation which affects their molecular shape and colour.
