Question
Examples of decomposition include:
- 2H2O2 → 2H2O + O2
- 2NaCI → 2Na + CI2
- Two of the above
- NH3 + H2O → NH4OH
Hint:
A decomposition reaction can be defined as a chemical reaction in which one reactant breaks down into two or more products.
The correct answer is: Two of the above
Both of the above reactions are the examples of decomposition reaction.
- 2NaCI
2Na + CI2 and 2H2O2 2H2O + O2
- In both reactions, the reactant breaks down into two products.
- During the reaction, a single substance decomposes and form two or many substances.
2Na + CI2 and 2H2O2 2H2O + O2
