Give the hybridization of each molecule and its geometry.
(7) Ammonia (1 nitrogen, 3 hydrogens)
Ammonia contains three sigma bonds and one unshared pair of electrons, so the hybridization is and the geometry is trigonal pyramidal.
(8) Carbon monoxide (1 carbon, 1 oxygen)
Triple bonds contain one sigma bond and two pi bonds, and each of the atoms has one unshared pair of electrons, so the hybridization is sp. The geometry is linear.
