Answer:
b ,Word equations give qualitative information about the reaction.
Explanation:
Word equation can give only qualitative information about reactants and products. While formula equation gives quantitative information about reactant and products.
For example:
Photosynthesis reaction:
It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.
Word equation:
Carbon dioxide + water → glucose + oxygen
water is supplied through the roots, carbon dioxide collected through stomata and sugar and oxygen are formed. This equation only provide the qualitative data which type of reactants and product are present.
Formula equation:
6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂
water and carbon dioxide react to form sugar and oxygen.
it is known from balanced chemical equation that 6 moles of carbon dioxide react with the six moles of water and created one mole of glucose and six mole of oxygen.
