Carbon has an atomic number of 6, but the following orbital notation for carbon is incorrect. explain the error in terms of the rules for electron arrangements.
carbon:
1s is filled. 2s is filled. 2p is shown to contain two electrons in one orbital and no electrons in the other two orbitals.

An atom of which element reacts with an atom of hydrogen to form a bond with the greatest degree of polarity ?

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.
