Answer:
.The concentration of N2O4(g) and the concentration of NO2(g) must be constant.
Explanation:
N2O4(g)<--------> 2NO2(g)
At equilibrium, all the concentrations of species involved in the equilibrium expression remain constant. This is because, at equilibrium, the rate of forward reaction equals the rate of reverse reaction. The concentration of the system does not change with time. The relative concentration of each specie, remain steady at equilibrium.
I found a similar question, so I think this can be taken as our problem because you seem to forgot including the picture. So, for letter a, the answer is: they represent different compounds. As you can notice, the CH₂CH₃ and CH₃ are both on the top side for the left figure, while the CH₃ and CH₃ are on the top side of the right figure. They are cis-trans isomers. The left figure is trans-2-pentene while the left figure is cis-2-pentene.
2-8-18-6 is the electron configuration. not sure what the other person was saying lol
