What does the negative value indicate about the reaction A student conducting a calorimetry investigation determines a negative and 8710H?

A negative value in a calorimetry investigation typically indicates that the reaction is exothermic, meaning it releases heat to the surroundings. In this case, the reaction associated with the negative value of -8710 J suggests that the system lost energy, resulting in a decrease in enthalpy. This indicates that the products of the reaction have lower energy than the reactants.
