Use the observations about each chemical reaction in the table below to decide the sign (positive or negative) of the reaction enthalpy ΔΗ and reaction entropy AS Note: if you have not been given enough information to decide a sign, select the "unknown" option reaction observations conclusions is one) B Crystallization of a pure compound is spontaneous only below 10. °C ASİS (pick one) This reaction is always spontaneous, but proceeds slower at temperatures below | is (pick one) (pick one) ΔΗ The reverse of this reaction is always spontaneous but proceeds slower at temperatures below 100. °C is (pick one) As is (pick one)

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

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.
