1. NH_cuatro + and S 2?
2. Al step three+ and PO₄ 3?
3. Fe 2+ and PO₄ 3?

1. Because the ammonium www.sugardaddydates.net/sugar-daddies-uk/sheffield/ ion has a 1+ charge and the sulfide ion has a 2? charge, we need two ammonium ions to balance the charge on a single sulfide ion. Enclosing the formula for the ammonium ion in parentheses, we have (NH₄)₂S. The compound’s name is ammonium sulfide.
2. Because the ions have the same magnitude of charge, we need only one of each to balance the charges. The formula is AlPO₄, and the name of the compound is aluminum phosphate. Weiterlesen →
