Water (h20) is composed of the same element as hydrogen peroxide (h202) how do their properties compare?
2 answers:
The formation of compound takes place by the combination of two or more different atoms. The combination of atoms takes place in a definite proportions. Compounds with different proportions of atoms have different properties.
Water () is composed of the same element as hydrogen peroxide (
) that is hydrogen (
) and oxygen (
). The combination of hydrogen and oxygen atoms in water is in
ratio whereas the combination of hydrogen and oxygen atoms in hydrogen peroxide is in
ratio. So, the properties of water and hydrogen peroxide are different as the arrangement of atoms is different in the compound.
Hence, the correct option is they have different properties because the arrangement of atoms is different.

Explanation:
Rate law is defined as the rate of a reaction is directly proportional to the concentration of reactants at constant temperature.
= k
where, k = rate constant
n = order of reaction
For the given reaction,
Hence, its rate will be as follows.
Rate =
Also, it is known that slowest step in a chemical reaction is the rate determining step.
Hence, for the given rate law correct reaction is as follows.
Step 1 : (slow)
Balancing this equation it becomes (slow)
Step 2: (fast)
