The difference in the reactivity of metals accounts for why some metals will react with hot water but not with cold water. For example, aluminum is less reactive than sodium and will only react with hot water but not cold water.

<h3>What is reactivity of metals?</h3>

The reactivity of metals is the ability of a metals to lose electrons.

The reactivity of metals generally decreases from left to right across the periodic table but increases on going down a group.

Due to the differences in reactivity of metals, some metals are more reactive than others.

For example, the reactive metals sodium, potassium and calcium react with cold water to with differing degree of spontaneity to liberate hydrogen.

Some other metal like aluminum, zinc, and iron can only react with hot water or steam to liberate hydrogen.

Therefore, the reactivity of a metal will determine if it will react with cold water or hot water.

Use the reaction equation and bond energies to answer the question.

Arisa [49]

This problem is providing us with the chemical equation for the decomposition of water to hydrogen and oxygen, the involved bond energies and asks for the total energy of the reaction as well as whether it is endothermic or exothermic. At the end, one comes to the conclusion that it is exothermic because the total energy is -425 kJ.

<h3>Bond energy:</h3>

In chemistry, bond energies are defined as the necessary energy to break a bond between two atoms. In this case, we see that water, H2O has two H-O bonds and hydrogen and oxygen have two H-H and one O=O bonds, respectively.

Thus, we write the following heat equation, which comprises the aforementioned bond energies and the stoichiometric coefficients in the reaction:

$\Delta H=2*\Delta H_{H-O}-(2*\Delta H_{H-H}+\Delta H_{O=O})$
