Final answer:
The ratio of elements in H2O2 and H2O is different because they are different compounds. In H2O, the ratio of hydrogen (H) to oxygen (O) is 2:1. However, in H2O2, the ratio of hydrogen to oxygen is 1:1.
Step-by-step explanation:
The ratio of elements in H2O2 and H2O is different because they are different compounds. In H2O, the ratio of hydrogen (H) to oxygen (O) is 2:1. However, in H2O2, the ratio of hydrogen to oxygen is 1:1. This means that for every one oxygen atom, there is one hydrogen atom in H2O2.
To understand this better, we can look at their chemical equations:
- H2O2: 2 H2O2 → O2 + 2 H2O
- H2O: 2 H2 + O2 → 2 H2O
In these equations, we can see that the ratios of hydrogen and oxygen atoms are different for each compound.
