Was this reaction exothermic or endothermic?
|Endothermic Reactions||Exothermic Reactions|
|Heat is absorbed by reactants to form products.||Heat is released.|
|Heat is absorbed from the surroundings; as a result, the surroundings get cold.||Heat is released by the reaction to surroundings; surroundings feel hot.|
|ΔHrxn is positive||ΔHrxn is negative|
