El ácido pantoténico (vitamina B5) es una vitamina soluble en agua. Una solución contiene 70 g de ácido pantoténico (C9H17NO5) disuelto en 2113 g de agua a 55°C, calcule el porcentaje en masa de ácido pantoténico en la disolución y la Molaridad de la disolución.

the correct answer is a

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

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.
