The change in the internal energy of the system is -4511.8 J.
<h3>What is the change in the internal energy?</h3>
We know that according to the first law of thermodynamics, energy can neither be created nor destroyed but can be transformed from one form to the other.
Now we know that;
ΔE = q + w
ΔE = Change in internal energy
q = heat absorbed or evolved
w = work done
Now we have;
q = - 134.8 J (The system losses heat)
w = PdV
w = 5.73 (1.00 - 8.540)
w = -43.2 Latm or -4377 J
Then we have;
ΔE = - 134.8 J + (-4377 J)
ΔE = -4511.8 J

Answer : C
Explanation:
a star produces energy by combining two atoms into one creates a powerful burst of energy
2Mg+O₂⇒2MgO
It can be a combustion reaction, or it can be a combination reaction
