+2
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 oxidation state of magnesium in magnesium hydroxide is +2 no matter what reaction you are looking at.
The oxidation state of magnesium in magnesium hydroxide is +2 no matter what reaction you are looking at.
In the reaction Mg + HO → Mg + H, the oxidation state of each hydrogen atom in H (which is diatomic hydrogen, H₂) is 0. This is because in its elemental form, hydrogen exists as H₂, and elements in their natural state have an oxidation state of zero.
The oxidation state of magnesium in magnesium hydroxide is +2 no matter what reaction you are looking at.
The oxidation state of Mg2+ is +2. Magnesium typically forms cations with a +2 charge by losing 2 electrons.
+2
Mg has an oxidation state of +2 & hydroxide has the oxidation state of -1. Formula of Magnesium hydroxide is Mg(OH)2
