The answer will be A & B not only because it makes sense but evaporation is taking water away not adding to (gaining)
The equivalency point is at the point of the titration where the amount of titrant added neutralize the solution. When it’s a strong acid strong base titration, the equivalence point will be 7. When it is a weak acid strong base, the equivalence point it more basic (the exact number depends on what acid and base you use). And when it is a strong acid weak base, the equivalence number is more acid (the exact number depends on what acid and base you use). Hope this helps!
The answer is number 1 - energy is emitted
Energy is released when an atom in an excited state returns to the ground state.
