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

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.

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.
