Ionization energy is the energy needed to remove one electron from an atom in the gaseous state.
Ionization energy (IE) is the force needed to ionize a neutral atom or cation when it is in its gaseous state. Ionization potential is another name for IE. Ionization energy is conceptually defined as an element's affinity for its outermost electron (an electron it already has in its valence shell).
The least amount of energy needed to ionize an atom is needed to remove an electron from its ground state. Across the periodic table, there is a regular increase in ionization energy from top to bottom and left to right.

Answer:
3Cu+ 8HNO3----> 3Cu(NO3)2 + 2NO +4H2O
Explanation:
5Fe2(SO4)3 + K2SO4 + 2MnSO4 + 8H2O
Answer:
38.9%
Explanation:
below, determine the mass percent of Fe3+ in a 0.6450 g sample of iron ore, if 22.40 mL of a 0.1000 M stannous chloride, SnCl2(aq), solution is required to completely react with the Fe3+ present in the ore sample. The chemical equation for the reaction is
2 Fe3+ (aq) + Sn2+ (aq) →2Fe2+ (aq) + Snº+(aq).
O 19.40%
O 6.196%
O 38.79%
O 9.697%
2 Fe3+ (aq) + Sn2+ (aq) →2Fe2+ (aq) + Snº+(aq).ole of Sn2+
for every mole of Sn2+, tere are 2 moles of Fe3+
- 22.4/1000L of 0.1000 M Sn2+ = 22.4 X 0.10/1000 = 0.00224 mole
so there are 0.00224 X 2= 0.00448 moles Fe3+
iron atomic mass is 56
56 X 0.00448 = 0.251 gm Fe3+
so the mass % of the Fe3+ in the 0.645 gm iron ore sample is
(0.251/0.645) X 100 = 38.9%
