2H2O ==> 2H2 + O2
Oxidation number of H on the left is 1+ and on the right it is zero. H has been reduced.
Oxidation number of O on the left is 2- and on the right it is zero. O has been oxidized.
YES, this is a redox reaction.

Hydrogen is Oxidized:
H2 --> 2H+
Oxygen is Reduced
O2 --> 2O-

What type of reaction is 2H2O 2H2 plus O2?
2H2O--->2H2 + O2 is a redox reaction because electrons are exchanged during electrolysis.
Can you tell a redox reaction which is also a combination reaction?
2Mg + O2------> 2MgO
Is 2HgO equals 2Hg plus O2 an oxidation reduction reaction?
i can't really read that reaction but! if there is an element by itself in either the reactant or the product side of the reaction QUICKLY think REDOX because the oxidation states for ANY element is 0 by themselves and when they form compounds they either oxidize or reduce to their oxidation state hope i helped
What type of chemical reaction is c5h12 plus o2 equals co2 plus h2o?

Is 2FeSO4 Fe2O3 plus SO2 plus SO3 a redox reaction?
No, there is no change in any oxidation states.
When magnesium ribbon is ignited it gives off a white fume of magnesium oxide. What is this type of reaction?
The reaction is 2Mg + O2 ----> 2MgO Mainly it is a Composition reaction (also called as combination or syntesis reaction). But also catogrised in redox reaction & combution reaction.
