When 12.00 grams of CoS * O_{4} hydrate are heated , the solid loses 5.38 grams of water Assuming that the residue is anhydrous , find the formula for the water

a electronegativity decreases beacuse the size of nucleus is bigger.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
