Write the formula for a complex formed between fe3 and ethylenediamine (nh2ch2ch2nh2), with a coordination number of 6.

We have to get the formula of the complex formed between Fe³⁺ and ethylenediamine.

The formula of the complex is: [Fe(en)₃]³⁺, where, en is abbreviation of ethylenediamine.

Ethylenediamine (en) is a bidentate ligand as it contains two donating sites (-NH₂ groups). Three ethylenediamine co-ordinate to central metal ion, Fe³⁺ and forms [Fe(en)₃]³⁺ with a co-ordination number of six.

the answer is a

photosynthesis

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
