a systematic error was not closing the open part of the flask in time after putting in the catalyst, so some of the gas will escape and we will always record less volume of gas produced than is produced. What is a way of reducing this error?

a random error is leaving droplets of water in the flask where the reaction takes place: there's an uneven amount every time and this dilutes the hydrogen peroxide solution, which leads to inaccurate results. What's a way of reducing this error?

another random error is using a stopwatch to time the reaction: we will always either stop a bit earlier or a bit later (inconsistent) as well as start a bit earlier and end a little later. what's a way to reduce this error?

another random error is weight of reactant kept flickering between two numbers due to the difference in air pressure, so we chose the number in between to minimize the error however this still will lead to inaccurate results
