Question

Sort the chemical reactions based on whether they absorb or release energy. respiration in cellsproducing electric currentburning a candlebaking breadactivating a cold packphotosynthesis

Answer 1

The chemical reactions that absorb energy are called endothermic reactions. These reactions absorb more energy than they release. From the given options endothermic reactions are: respiration in cells, photosynthesis, activating a cod pack

The chemical reactions that release energy are called an exothermic reactions: producing electric current, burning a candle, baking bread.

Answer 2

Answer:

Releases Energy; burning a candle, producing electric current, and respiration in cells.

Absorbs Energy; activating a cold pack, baking bread, and photosynthesis.

Explanation:

Burning a candle releases heat energy into the surrounding area. The respiration process in cells does not produce any energy, so it must release it. Activating a cold pack absorbs energy in order to activate. Baking bread absorbs heat when baking, it releases it when cooling. Photosynthesis absorbs energy at the beginning of the process before releasing/using it.
