  1. Stellar equilibrium is the balance of reactions and forces that allows a star to maintain its size and shape.

AWhat reactions occur within a star in stellar equilibrium?
BWhat effect do these reactions have on the star?
CWhat forces hold a star together in stellar equilibrium?

the nuclear fusion reaction occurs just outside the inner core, creating an explosive force that keeps the star 'inflated.' Gravitational pull toward the star's center of mass keeps enough pressure on the core to keep the heat and pressure necessary for fusion to occur.
I hope this will be the answer of all of your above questions :)

Answer:

A. Nuclear fussion reactions.

B. Generates an internal pressure that try to expand the star.

C. Gravity force and internal pressure.

Explanation:

In a star there is a balance between gravity force, that attracts the stellar gas towards the center and compressing it, and the pressure due to nuclear fusion reactions that occur within the star, that acts in the opposite direction to gravity trying to expand the star. Therefore, the star is in equilibrium and adopts a stable spherical shape.
