What contains more energy-endothermic or exothermic expain

(In endothermic reactions the enthalpy of the products is greater than the enthalpy of the reactants.)

- Because reactions release or absorb energy, this affects the temperature and the surroundings.

- Exothermic reactions heat up the surroundings while on the other hand endothermic reactions cool them down.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
