This reaction would not take place. In Chemistry, there is a list called the Activity Series that dictates which metals can replace others in single and double replacement reactions. Hydrogen is more reactive than copper and thus the copper will not be able to react with the Hydrogen Peroxide.
The equation as given can not be balanced, because it is incomplete: When hydrogen peroxide decomposes to produce water, it also produces oxygen. A proper, balanced equation for the reaction is 2 H2O2 -> 2 H2O + O2.
If you had the equation of H2O2(aq) ==> H2O(l) + O2(g), it wouldn't be balanced, so is incorrect. If it were 2H2O2 ==> 2H2O + O2, then it would be balanced, and H2O2 would be an example of a disproportionation reaction, where H2O2 is both the oxidizing and reducing agent, i.e., the O is both oxidized and reduced to form H2O and O2. Not sure if this is what you are looking for as the question is rather vague.
Cu(NH3)SO4 or [CU(NH3)4]SO4
Mg + Cu(NO3)2 -> Mg(NO3)2 + Cu
The balanced equation would be; C25H52(s) + 38 O2(g) -> 25 CO2(g) + 26 H2O(l)

H2O2 + 2 KI --> 2 KOH + I2
The balanced equation for this decomposition reaction is 2 H2O2 -> 2 H2O + O2.
No. It would have to be H2O2 - H2 = O2 in order to be balanced.

the balanced equation is Na2S2O3 plus H2O2 yields 2NaOH plus H2S2O3 plus O2.
The balanced reaction for N2H4 + H2O2 --> N2 + H2O is N2H4 + 2H2O2 --> N2 + 4H2O
Cu(NH3)SO4 or [CU(NH3)4]SO4
Mg + Cu(NO3)2 -> Mg(NO3)2 + Cu
