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.
2H2O--->2H2 + O2 is a redox reaction because electrons are exchanged during electrolysis.
This is an oxidation reaction of N from -3 (in NH3) to +2 (in NO) oxidation value. 4 NH3 + 5 O2 --> 6 H2O + 4 NO
A redox (oxidation-reduction) reaction involves the transfer of electrons between reactants. For example, the reaction between iron (Fe) and oxygen (O2) to form iron oxide (Fe2O3) is a redox reaction. In this reaction, iron atoms lose electrons (oxidation) while oxygen atoms gain electrons (reduction).
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
The H2O2 redox reaction occurs when hydrogen peroxide (H2O2) is broken down into water (H2O) and oxygen (O2) through the transfer of electrons. This reaction is important in chemical processes as it can be used as a disinfectant, bleaching agent, and in various industrial applications.
yes

No, there is no change in any oxidation states.

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.
decomposition reaction
The product for the reaction between PbO2 and O2 is PbO2.
A chemical change, redox reaction: 2Fe(s) + O2(g) --> 2FeO(s)
endothermic
This is a decomposition reaction. KNO3 decomposes into KNO2 and O2 when heated.
