two chemicals react in an endothermic reaction. what can be known about this reaction?\nheat is absorbed because the old substance needs more energy to break its bonds.\nheat is released because the old substance needs less energy to break its bonds.\na precipitate will form as a result of the reaction.\na gas will form as a result of the reaction.
Answer
Brief Explanations:
In an endothermic reaction, heat is absorbed. This is because energy is required to break the bonds in the reactants. The old substances need more energy to break their bonds, so heat is taken in from the surroundings. Precipitate or gas formation is not a characteristic specific to endothermic reactions.
Answer:
Heat is absorbed because the old substance needs more energy to break its bonds.
