Enter your answer in the provided box. High levels of ozone (O3) make rubber deteriorate, green plants turn brown, and cause people to have difficulty breathing. Calculate ΔG at 298 K for the formation of 1 mole of O3 from O2 in urban smog, where [O2] = 0.210 atm and [O3] = 5.00 × 10−7 atm.

Two red blood cells each have a mass of 9.0 multiply.gif 10-14 kg and carry a negative charge spread uniformly over their surfaces. the repulsion arising from the excess charge prevents the cells from clumping together. one cell carries −2.50 pc of charge and the other −3.10 pc, and each cell can be modeled as a sphere 7.5 μm in diameter. (a) what speed would they need when very far away from each other to get close enough to just touch? assume that there is no viscous drag from any of the surrounding liquid. answer is: 321 m/s how do i find this (b) what is the maximum acceleration of the cells in part (a)? answer is: 1.38e+10 m/s2 how did they find this answer
