What's the difference between a word equation and a formula equation?

a, Word Equations give quantitative information about the reaction

b ,Word equations give qualitative information about the reaction.

c, word equations and formula equations are the same

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.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
