Tah5 has been predicted to have c4v symmetry, with a calculated axial h—ta—h angle of approximately 117.5°. using the six-step approach described in section 5.4.2, describe the bonding in tah5 on the basis of matching group orbitals and central atom orbitals according to their symmetry. (see c. a. bayse, m. b. hall, j. am. chem. soc., 1999, 121, 1348.)

For each of the following compounds, write the formula then predict whether it would be a strong, weak, or non-electrolyte when placed in di water. for the ionic compounds only, put (s) or (aq) after the forrmula formula strong, weak or non electrolyte? a calcium hydroxide b. silver carbonate c. lead(ii) sulfate d. phosphorus trifluoride e. sodium phosphide f barium sulfate g. strontium acetate h. zinc nitrate
