I need help ASAP Place the following orbitals in order of increasing energy:
1s, 3s, 4s, 6s, 3d, 4f, 3p, 7s, 5d,

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.
