Question

3 Drag each tile to the correct location. Classify the reactions as endothermic or exothermic. The reaction between ammonium nitrate and water absorbs heat from the surrounding environment. Three drops of concentrated sulfuric acid added to 100 milliliters of water in a beaker makes the beaker hot. Ammonium chloride dissolved in a beaker of water makes the beaker cold. Uranium atoms are split to produce nuclear energy. Water separates into hydrogen and oxygen when an electric current is run through it. Methane and oxygen are combined to produce methanol and heat.

Answer 1

In an exothermic reaction heat is released by a chemical reaction. In an endothermic reaction heat is absorbed by a chemical reaction.
