zero- H2 is the elemental form- by definition the ON# is zero
The oxidation state (or number) is zero. This is true for any element in any of its allotropic elemental forms.
For 2HCl(g) ==> H2(g) + Cl2(g) the Keq = [H2][Cl2]/[HCl]^2
The balanced chemical equation for the conversion of H2(g) to H(aq) and H-(aq) is: 2H2(g) - 2H(aq) 2e-
Zero The oxidation number of an element in any of its elemental forms (allotropes) is always zero
The oxidation number of H in NaHSO4 is +1. In this compound, Na has an oxidation state of +1, S has an oxidation state of +6, and O has an oxidation state of -2. By adding up the oxidation states and solving for H, it is determined to be +1.
The answer is 0
In:(H2)g oxidation state: 0 In:(O2)g oxidation state: 0 In:(H2O)l oxidation state: H: +1 and O: -2
The oxidation state (or number) is zero. This is true for any element in any of its allotropic elemental forms.
Simply remember OIL RIG. Oxidation Is Loss (of electron) and Reduction Is Gain (of electron). In the case of MnO4-(aq) + 8H+(aq) + 5e- --> Mn2+(aq) + 4H2O(l) H is the oxidizing agent, because it causes Mn to be oxidized to Mn2+.
Hydrogen gas (H2) Oxidation number is 0. Hydrogen (H+) is +1.
For 2HCl(g) ==> H2(g) + Cl2(g) the Keq = [H2][Cl2]/[HCl]^2
The balanced chemical equation for the conversion of H2(g) to H(aq) and H-(aq) is: 2H2(g) - 2H(aq) 2e-

•This brings us to a new term, the Eh •Eh is a measure of the oxidation state of a fluid •Low Eh- reducing •Positive Eh- oxidizing •All redox reactions referenced to H electrode: -H+ + e- > ½ H2
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.
