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.
I believe it’s 3 hours since every hour it’s 80km so 3x80 is 240 so it would be 3 hours.
Answer:
B. K valence electron of K experiences a lower effective nuclear charge the valence electrons of Ca
10 miles per hour because 500 divided by 50 is 10
Answer:
A. (CH3)3C-I reacts by SN1 mechanism whose rate is independent of nucleophile reactivity.
Explanation:
We must recall that (CH3)3C-I is a tertiary alkyl halide. Tertiary alkyl halides preferentially undergo substitution reaction via SN1 mechanism.
In SN1 mechanism, the rate of reaction depends solely on the concentration of the alkyl halide (unimolecular mechanism) and is independent of the concentration of the nucleophile. As a result of this, both Br^- and Cl^- react at the same rate.
