These types of reactions are called endothermic reactions. This is when the system absorbs the heat from the surrounding. In this case, the system is the chemical reaction and the environment is the direct vicinity of the chemical reaction. You notice that the pack becomes cold because heat from the surrounding is being absorb.
The bonds involved in this substance includes ionic bonding and polar covalent.

Answer: An acid contains more hydrogen ions than hydroxide ions.
Explanation:
An acid is defined as the chemical compound which has a high concentration of hydrogen ions. They are considered as proton donors and they act as proton
donors when they have high concentration of hydrogen ions.
A base is defined as a chemical substance which has high concentration of hydroxide ions. They are considered as proton acceptors and they act as proton
acceptors when they have low concentration of hydrogen ions.
Hence, an acid is contains more hydrogen ions than hydroxide ions.
