10 ml of a 3% hydrogen peroxide solution is added to live test tubes. as the hydrogen peroxide decomposes to produce
oxygen gas, the rate of oxygen production is rated on a scale of 0 5.0 meaning "no oxygen and 5 me
other four test tubes of hydrogen peroxide, five drops of additional solutions are added. the solutions are indicated in the
data table as well as the rate of oxygen production for each the students concluded that iron compounds are a catalyst for
the decomposition of hydrogen peroxide

another experiment was conducted by the students using hydrogen peroxide. the table shows the results of an experiment in
which students placed hydrogen peroxide on several food samples and recorded the relative amount of fire that each produced

the fizz was produced by oxygen bubbles released by the action of the enzyme catalase, which is found in almost every living cell
comment on how the new results impacts the conclusion from the initial experiment
