The reaction represented by H₂O → H₂(g) + O₂(g) is a decomposition reaction. In this reaction, water (H₂O) is broken down into its constituent elements, hydrogen gas (H₂) and oxygen gas (O₂), typically through the process of electrolysis or thermolysis. Decomposition reactions involve the separation of a compound into simpler substances.
In the reaction ( \text{Mg} + 2 \text{H}_2\text{O} \rightarrow \text{Mg(OH)}_2 + \text{H}_2 ), the oxidation state of each hydrogen atom in ( \text{H}_2 ) (denoted as ( \text{H}_2(g) )) is 0. This is because in diatomic molecules like ( \text{H}_2 ), the atoms are in their elemental form, and their oxidation state is defined as zero.
The correct form for the equilibrium constant expression for this reaction is Kc = [HF]^2 / ([H2] * [F2]), where the square brackets denote molar concentrations of each species at equilibrium.
The equilibrium constant, K_eq, for the reaction 2HCl(g) ⇌ H2(g) + Cl2(g) is equal to the concentration of H2 and Cl2 divided by the concentration of HCl squared, as products are in the numerator and reactants in the denominator.

Its 0
Keq = [H2O][CO] [H2][CO2]
Yes, the equation obeys the law of conservation of matter. The number of atoms for each element is the same on both sides of the equation, indicating that no atoms are created or destroyed during the reaction.

The reaction 2Na(s) + 2H2O(l) → 2NaOH(s) + H2(g) is a single displacement reaction, where sodium (Na) displaces hydrogen from water (H2O). This is also an exothermic reaction, as it releases energy in the form of heat when sodium reacts with water. The reaction produces sodium hydroxide (NaOH) and hydrogen gas (H2).
