Onsider the isomerization of butane with an equilibrium constant of . The system is originally at equilibrium with [butane] = 1.0 M and [isobutane] = 2.5 M. a If 0.60 mol/L of isobutane is suddenly added and the system shifts to a new equilibrium position, what is the equilibrium concentration of each gas? = M = M

What shape would a molecule with two bound groups and two lone pairs have?

Given the data below for the reaction, 2 a + 2 b + 4 c => d + e + 3 f, the reaction is fill in the [ ] order in a, fill in the [ ] order in b, fill in the [ ] order in c and fill in the [ ] order overall.
