Average Graduate Management Admission Test (GMAT) scores can be a good indicator of student quality -- often, schools with higher average GMAT scores are recognized more broadly for the quality of their graduates. The best place to start is www.mba.com/military.
For example, FeSO 4 is named iron(2+) sulfate (with the 2+ charge on the Fe2+ ions balancing the 2â charge on the sulfate ion), whereas Fe 2 (SO 4) 3 is named iron(3+) sulfate (because the two iron ions in each formula unit each have a charge of 3+, to balance the 2â on each of the three sulfate ions).
Explain why ionic compounds do not conduct electricity in their crystalline form. Electricity can only be conducted when ions are freely moving in separate positive and negative charges (as in the aqueous form and molten form). In their crystalline form, the ions in the ionic compound are locked tightly in one place and the positive and negative balance out to make the overall structure neutral.
