The word equation for the formation of water would be: hydrogen + oxygen --> water. a hydrogen molecule (h2) and an oxygen molecule (o2) are the reactants. water (h2o) is the product. when hydrogen and oxygen combine to form water, which term is used to describe the water? a) product b) catalyst c) reactant d) enzyme

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
