Explanation:

When heat is absorbed by reactants in a chemical reaction then the reaction is known as endothermic reaction.

Whereas when heat is released by reactants in a chemical reaction then the reaction is known as exothermic reaction.

1. When \Delta H is positive then it means heat is absorbed by reactants and reaction is endothermic.

2. When E_{2} < E_{1}, this means energy of products is less than the energy of reactants. Therefore, it is exothermic in nature.

3. When energy is absorbed then reaction is endothermic.

4. When E_{2} > E_{1}, this means energy of products is greater than the energy of reactants. Therefore, it is endothermic in nature.

5. When [tex]\Delta H is negative then it means heat is released by reactants and reaction is exothermic.

What layer of the Sun is the location for nuclear fusion?
svp [43]
The core is at the center. It the hottest region, where the nuclear fusion reactions that power the Sun occur. Moving outward, next comes the radiative (or radiation) zone. Its name is derived from the way energy is carried outward through this layer, carried by photons as thermal radiation.
