Question

List two combinations that resulted in endothermic reactions.

Answer 1

any example?

Answer 2

idk

Answer 3

It would be any chemical reaction that absorbs heat from its environment.

Examples:
- Dissolving ammonium chloride in water.
- Combining oxygen with nitrogen (N2) to form nitric oxide (NO) is an endothermic reaction. In a nitrogen molecule, the atoms are held together by a very strong triple bond. The energy required to break this bond is greater than the energy released by the formation of nitric oxide, so the reaction is endothermic
