This reaction is exothermic because the system (the aqueoud solution) is transferring heat to its surroundings (the calorimeter) so this eliminates two responses. Since the heat is being transferred to the surroundings, the water that's in the calorimeter in this case, it is causing the water molecules to heat up and thus an increase in the kinetic energy of the water molecules since temperature affects kinetic energy

Seven diatomic elements are H₂, Cl₂, N₂, F₂, Br₂, I₂ and O₂.
<h3>Which are diatomic molecules?</h3>
Diatomic molecules are those molecules in which two atoms of same elements are present, and they are combined to attain the stability.
The seven diatomic molecules which are exist in the chemistry are:
- Hydrogen gas (H₂)
- Chlorine gas (Cl₂)
- Nitrogen gas (N₂)
- Fluorine gas (F₂)
- Bromine gas (Br₂)
- Iodine gas (I₂)
- Oxygen gas (O₂)
Hence H₂, Cl₂, N₂, F₂, Br₂, I₂ and O₂ are 7 diatomic molecules.
