Question: Why is the last part negative Example 2 - Reaction Enthalpy A reaction warms 100 g solution by 7.5.C. (c = 4.184 J/g.C). Moles reacted

Why is the last part negative

Example 2 - Reaction Enthalpy A reaction warms 100 g solution by 7.5.C. (c = 4.184 J/g.C). Moles reacted = 0.055. q = 100(4.184) (7.5) = 3138 J Exothermic - q
