K = 0.058 yr (constant)
Fraction of the pesticide = 36 years/12 = 3 half-lives , so around 1/8 left
when 99.9 % decomposed, 0.1 % is left , so the fraction is 0.001. To reach this point, it will take around +/- 120 years
A mole of CO2 = 2 moles of O2
8 CO moles x 2 =
16 moles
Yes that's the right answer
