The percentage decrease in Ofnetite over the first two hours is 99.96%. This is because the half-life of Ofnetite is 25 minutes, which means that the amount of the substance decreases by half at every 25 minute interval. After two hours, there would be 6 intervals, giving a total decrease of 6 halvings or a 99.96% decrease.
