Question

Describe the appearance of the water and the hydrogen peroxide. How are they similar and how are they different?

Answer 1

Hydrogen Peroxide (H2O2) is a colourless liquid that resembles water in many respects. Its physical properties are very similar to those of water, except that it is 40% denser. The single bond between the two oxygen atoms is weak, so that H2O2 readily fragments into either H and HO2 or two OHs.

Step-by-step explanation:

Answer 2

The bonds that hold H2O2 together break apart and the atoms are rearranged to form water (H2O) and oxygen (O2) molecules. This happens slowly in store-‐bought hydrogen peroxide, so even in dark bottles, it will 'expire' in a year, or less if it's opened. ... And higher concentrations of H2O2 produce more oxygen.
