Nitrogen dioxide, a pollutant that contributes to photochemical smog, is formed by a series of two reactions. N2(g)+O2(g)⇌2NO(g) Kc1=4.3×10−25 2NO(g)+O2(g)⇌2NO2(g) Kc2=6.4×109 N2(g)+2O2(g)⇌2NO2(g) Kc(overall)=? Choose the equilibrium constant expression for the overall reaction.

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above

its going to be mutualism cuz they both benefit from the relationship.

personal, she chose to do it.

the dissolution of polymer can be thermodynamically described in 2 steps.
