What is the angle between two of the nitrogen-hydrogen bonds in the ammonium (NH4+) ion?

Arlecino [84]

Answer:

109° 27'

Explanation:

The ammonium ion is tetrahedral in shape, all the HNH bonds are exactly at the tetrahedral bond angle since there are only bond pairs in the structure and no lone pairs. Recall that lone pairs decrease the bond angke from the ideal value in a tetrahedron due to higher repulsion.

Molten zinc chloride can be electrolysed.

Crank

Answer: The products of electrolysis are Zn(l) and $Cl_2$ gas

Explanation:

Electrolysis of a subastance is breaking it into its constituents by the action of electrical current.

In the electrolysis of molten zinc chloride, zinc metal is produced at the cathode which is a negative electrode and chlorine gas produces as the anode which is a positive electrode.

$ZnCl_2(l)\rightarrow Zn^{2+}+2Cl^-$

At anode : $2Cl^-(l)\rightarrow 2e^-+Cl_2(g)$

At cathode : $Zn^{2+}(l)+2e^-\rightarrow Zn(l)$
