Which type of bond is broken by water or heat?

Hydrogen bond
Salt bond
Disulfide bond
Ionic bond

The correct answer is: Hydrogen bond

Water and heat have the ability to break hydrogen bonds because they are relatively weak compared to other types of chemical bonds. Salt bonds and ionic bonds are typically much stronger than hydrogen bonds, therefore water and heat do not have as much influence on breaking them. Disulfide bonds are also relatively strong, and while heat can break them, it often requires a higher temperature or more energy. Overall, hydrogen bonds are the most likely to be broken by water or heat because of their specific nature and relative strength.
