What is the equilibrium constant for the following reaction c + o2↔co2

C + O₂  =  CO₂
    ↓              ↓
reagents     products

Kc = products / reagents

Kc = [ CO₂ ] / [ C ] . [ O₂]

hope this helps!

There is like 5. not sure.

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
