Write a balanced chemical equation that expresses the reaction that will occur
during this experiment and that will convert hydrogen peroxide (h2o2) to oxygen
(o2) gas and liquid water (h2o).

The balanced reaction is: H2O2 -> H2O + (1/2) O2

However, this is a very awkward equation since it has a coefficient in fraction form.

Another way to write this equation is:

2 H2O2 -> 2 H2O + O2

Hope this helps.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
