Final answer:

The formula that is not correct is option b. BaHCO₃. The correct formula for barium bicarbonate should be Ba(HCO₃)₂ due to barium having a +2 charge and each bicarbonate ion having a -1 charge.

Step-by-step explanation:

To determine which formula is not correct, we can evaluate each option:

  • a. NH₄HSO₄ - Ammonium bisulfate, correct formula.
  • b. BaHCO₃ - Barium bicarbonate, this is an incorrect formula. The correct formula for barium bicarbonate would be Ba(HCO₃)₂ since barium has a +2 oxidation state and bicarbonate has a -1 charge. Therefore, two bicarbonate ions would be needed to balance the charge of one barium ion.
  • c. Al₂(SO₄)₃ - Aluminum sulfate, correct formula.
  • d. Ca(OH)₂ - Calcium hydroxide, correct formula.
  • e. LiH - Lithium hydride, correct formula.

So, the formula that is not correct is b. BaHCO₃.
