Iwas given a home work to research about hydrates , i have tried but i have not gotten any concrete information yet , i need the , definition , causes and control.

In chemistry, a hydrate is a substance that contains water or its constituent elements. The chemical state of the water varies widely between different classes of hydrates, some of which were so labeled before their chemical structure was understood. Anhydrous forms of hydrates are often used to absorb water, particularly during shipment of electronic and optical equipment. In chemistry labs, anhydrous forms of hydrates are used to remove moisture from the air and keep other substances dry

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

ok whats the question if not i cannot you i need question and need a thing to answer
