Just as the depletion of stratospheric ozone today threatens life on earth today, its accumulation was one of the crucial processes that allowed life to develop in prehistoric times. you must have the correct sig figs. 3 o2 (g) > 2 o3 (g)(a) express the rate of reaction in terms of the rate of disappearance of o2 and the rate of appearance of o3.(b) at a given instant, the rate of disappearance of o2 is 1.61 x 10^-5 mol/ls. what is the rate of appearance of o3?

-d[O2]/dt

d[O3]/dt= d[O2]/dt=1.61*10^-5molL-1

Explanation:

The rate if disappearance of reactant is the same as the rate at which it is converted to product or the rate at which the product appears. Hence the solution. This is because the reactant is directly converted to product.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.

explanation:

i would say b

explanation:

but i think i would need more information than that
