Identify each chemical reaction as endothermic or exothermic based on its description. Drag each tile to the correct location. Sodium bicarbonate reacts with citric acid. The temperature of the reaction mixture drops by 6.8°C. Zinc powder is stirred into a beaker containing copper(II) sulfate. The beaker feels warmer to the touch. Carbon in charcoal reacts with oxygen in the air. The reaction produces heat for cooking along with carbon dioxide. The chemical equation for hydrogen reacting with oxygen shows water and energy in the product. Cold packs are used to treat sports injuries. The temperature drop in the cold pack is activated by mixing ammonium nitrate with water. Salt water can treat a sore throat. Pouring salt into the water removes some of the energy from the water.
