Ammonia reacts with `Al^(3+)` to give precipitate of ____.

Which compound reacts with NH_(3) to give black precipitate ?

CoSO_(4)Cl.5NH_(3) exists in two isomeric forms 'A' and 'B'. Isomer 'A' reacts with AgNO_(3) to give white precipitate, but does not react with BaCl_(2) . Isomer 'B' gives white precipitate with BaCl_(2) but does not react with AgNO_(3) . Answer the following questions. (i) Identify 'A' & 'B' and write their structural formulas. (ii) Name the type of isomerism involved. (iii) Give the IUPAC name of 'A' and 'B'.

CaC_2 reacts with water to give:

Nitrogen gas reacts with metal A at room temperature to form white solid B. B on reaction with pungent smell of gas C along with the formation of D. D is used as antacid. C reacts with HCl to give white precipitate of E. Find A to E and write balanced chemical equations.

A metal complex having composition Cr(NH_(3))_(4)Cl_(2)Br has been isolated in two forms (P) and (Q). The form (P) reacts with AgNO_(3) to give a white precipitate. Readily soluble in dilute aqueous ammonia, whereas (Q) gives a pale yellow precipitate soluble in concentrated ammonia. Write the formula of (P) and (Q) and state the hybridisation of Cr in each. Calculate the magnetic moments (spin only value).

If a coordination compound, CoCl_(3).4NH_(3) is heated, it does not give out NH_(3) , while if the same reacts with AgNO_(3) solution, gives a white precipitate of AgCl. Write the structure and IUPAC name of the compound.
