They are called reactants.
Ions have an extra or lost an electron. Isotopes have different numbers of neutrons.
The answer is about 1/2 it rises very sloe
The decomposition reaction for hydrogen peroxide is given below:
2
→ 2
O + 
This is a decomposition reaction.
Reactions in which a reactant breaks into two or more products are known as Decomposition reactions.
AB → A + B
here, AB represents the reactant that begins the reaction, and A and B represent the products of the reaction
The decomposition reaction of decomposing hydrogen peroxide is exothermic. When the hydrogen peroxide undergoes a decomposition reaction, heat is also released along with water and oxygen.
Hence the reaction for decomposing hydrogen peroxide is :
2
→ 2
O +
