Researchers recorded that a certain bacteria population declined from 700,000 to 400,000 in 5 hours after the administration of medication. At this rate of decay, how many bacteria will there be 24 hours from the start of the experiment?
At 45°C, dinitrogen pentoxide (N2O5) decomposes into nitrous dioxide (NO2)and oxygen (O2) according to the law of uninhibited decay. An initial amount of 0.25 mole of dinitrogen pentoxide decomposes to 0.15 mole in 17 minutes. How much dinitrogen pentoxide will remain after 30 minutes? Howlong will it take until 0.01 mole of dinitrogen pentoxide remains?

Suppose that poaching reduces the population of an endangered animal by 4% per year. Further suppose that when the population of this animal falls below 70, it's extinction is inevitable. If the current population of the animal is 1500, when will it face extinction?
According to estimates, the global emissions of CO2 in the energy sector will total about 36 billion metric tons in 2020. The energy sector has been decarbonizing at a rate of 1% per year. estimated to be "decarbonizing" at a rate of 1% per year. Suppose that the energy sector continued to decarbonize at the historical rate of 1% per year. Estimate the amount of time it would take for global emissions of CO2 from the energy sector to drop below 8 billion metric tons per year. Round your answer to the nearest year.
