Answer:
final-intial temperature= enthalpy change
Organisms within each group are then further divided into smaller groups. These smaller groups are based on more detailed similarities within each larger group. This grouping system makes it easier for scientists to study certain groups of organisms.

Equation is;
2Na + Cl2 = 2NaCl
Looking at the options, the correct one is Sodium chloride.
It was disproved by the discovery of the electrons
