When pellets of NaOH(s) are added to a flask of water, it is observed that the temperature of the water increases as the pellets
Nataly [62]

Answer: It is an exothermic process because heat energy is absorbed by the water as the NaOH(s) dissolves in it.

Explanation:

Endothermic reaction : It is a type of chemical reaction where the energy is absorbed from the surrounding. In the endothermic reaction, the reactant are less than the energy of product. In endothermic reaction, the change in enthalpy is, positive

Exothermic reaction : It is a type of chemical reaction where the energy is released into the surrounding. In the exothermic reaction, the energy of reactant are more than the energy of product. In exothermic reaction, the change in enthalpy is, negative.

Thus as energy is absorbed by water, which has been released by NaOH, the process is exothermic.

  • so Br<Cl<F

2. Na K Li

  • ionization energy decreases we move down the group
  • so K<Na<Li

3. C N O F

  • ionization energy increases as we move across the peroid
  • so C<N<O<F
