<span> the electron configuration for the manganese atom [Ne]3s</span>²
The answer would be choice B because the energy decreased by 20 J
Energy + SO2(g) -----> S(g) + O2(g) is an edothermic reaction owing to te fact that energy is a reactant in the equation.
<h3>What is an endothermic reaction?</h3>
An endothermic reaction is one in wioch energy is supplied to the system in order to enable the breakdown of bonds. Hence, the reaction vessel feels cool as energy is withdrawn from the surroundings.
The reaction; Energy + SO2(g) -----> S(g) + O2(g) is an edothermic reaction since energy is a reactant in the equation.
