In a certain chemical reaction, the bonds of the products contain more energy than the bonds of the reactants. For the reaction to occur, which of the following best describes what occurred? A) Energy was added, so the reaction is endothermic. B) Energy was released, so the reaction is exothermic. C) Energy was released, so the reaction is endothermic. D) Energy was added, so the reaction is exothermic

Explanation:

The energy change in a chemical reaction is due to the difference in the amounts of stored chemical energy between the products and the reactants. This stored chemical energy, or heat content, of the system is known as its enthalpy.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
