Essay content:

As a result, the reaction was incomplete, leaving un-reacted products and reactants that weren’t produced yet and therefore any measurement of the reactants, oxygen and water, was skewed. The direct result was the low yield of oxygen as the reaction was stopped before all the oxygen was produced leading to the low percent yield...

Also, because the reaction didn’t use up all the hydrogen peroxide, the amount of “water” collected probably still had hydrogen peroxide, inflating the mass of the water leading to the high percent yield. The second source of procedural uncertainty comes from the use of two devices to collect the catalyst after the reaction had been finished...
