Answer is: 28 kJ.
Chemical reaction: A₂ + B₂ ⇄ 2AB.
Ea(forward) = 105 kJ/mol.
Ea(reverse) = 77 kJ/mol.
ΔH(reaction) = ?
<span>The enthalpy change of reaction is the change in the energy of the reactants to the products.
</span>ΔH(reaction) = Ea(forward) - Ea(reverse).
ΔH(reaction) = 105 kJ/mol - 77 kJ/mol.
ΔH(reaction) = 28 kJ/mol; this is endothermic reaction (ΔH <span>> 0).</span>

Tsunami waves are almost the same as ripples caused by throwing a rock into a pond. What is the major difference between the two
Daniel [21]

c. The energy source of tsunami waves is much greater

Explanation:

The major difference between a tsunami waves and ripple waves is that the energy source of tsunami waves is much greater compared to ripple waves.

Tsunami waves carry more energy compared to just a disturbance resulting from a ripple caused by dropping of a stone.

  • A tsunami is a large water wave caused by the displacement of water usually by an earthquake.
  • An earthquake is a releases elastic waves suddenly within the earth crust.
  • Water bodies at the epicenter are disturbed sending huge volume of energetic water loads to the land.
  • A ripple is just a product of a stone dropped inside the water.

Tsunamis are more energetic compared to ripples in water.
