Explain what kind of reaction is occurring When heat is given off or attracted at some stage in a chemical reaction it is called Thermo chemistry. In a hot pack a chemical reactions is refers to because of the mixed new substances that are forming from the push and shaking of the initial use. The heat pack has numerous chemical reactions; and energy is discharged in the structure of heat. When this reaction transpires, bonds are made between atoms which are often noticed as an exothermic reaction. As an effect, exothermic reactions create hot temperatures which

Unformatted text preview: active the process of the hot pack. Hot packs include a dry chemical in the form of a powder. The occurring reactions that take place are the discharge of water and then combine with the chemicals in the outer pouch. This will generate either an exothermic or endothermic reaction and from what we already know the hot pack is an exothermic reaction because, it is releasing energy. Typically, hot packs include calcium chloride or magnesium sulfate. When these chemicals are release the temperature will raise as the water is mixed to the hot pack....
