We have to get the formula of the complex formed between Fe³⁺ and ethylenediamine.
The formula of the complex is: [Fe(<em>en</em>)₃]³⁺, where, <em>en</em> is abbreviation of ethylenediamine.
Ethylenediamine (<em>en</em>) is a bidentate ligand as it contains two donating sites (-NH₂ groups). Three ethylenediamine co-ordinate to central metal ion, Fe³⁺ and forms [Fe(<em>en</em>)₃]³⁺ with a co-ordination number of six.
Answer:
ClO⁻(aq) + I⁻(aq) → Cl⁻(aq) + IO⁻(aq)
Explanation:
The reactions are:
(1) ClO⁻(aq) + H₂O(l) → HClO(aq) + OH⁻(aq) [fast]
(2) I⁻(aq) + HClO(aq) → HIO(aq) + Cl⁻(aq) [slow]
(3) OH⁻(aq) + HIO(aq) → H₂O(l) + IO⁻(aq) [fast]
By adding up the 3 equations we get:
ClO⁻(aq) + <em>H₂O(l)</em> + I⁻(aq) + <em>HClO(aq)</em> + <em>OH⁻(aq)</em> + <em>HIO(aq)</em> → <em>HClO(aq)</em> + <em>OH⁻(aq)</em> + <em>HIO(aq)</em> + Cl⁻(aq) + <em>H₂O(l)</em> + IO⁻(aq)
And by canceling common terms on both sides, we can get the overall equation:
ClO⁻(aq) + I⁻(aq) → Cl⁻(aq) + IO⁻(aq)
Therefore, the overall equation is ClO⁻(aq) + I⁻(aq) → Cl⁻(aq) + IO⁻(aq).

A:The half-life should be similar to the age of the object.
Explanation:
Hopefully this helps!
Calcium has electrons in more energy levels than magnesium. The number of electron in calcium atom is 20 which means 4 energy levels. (2 electron in first shell+ 8 electron in second shell+8 electron in third shell+ 2 electron in fourth shell). While number of electron in magnesium atom is 12 which means 3 energy levels. (2 electron in first shell+ 8 electron in second shell+ 2 electron in third shell). Also the Calcium third energy level contains more electron than magnesium.
