Answer is: concentration of ammonium ions are 7,14·10⁻¹⁴ M.<span>
Chemical reaction: 2NH</span>₃(l) → NH₄⁺(am) + NH₂⁻(am).<span>
Kam = 5,1·10</span>⁻²⁷.<span>
[NH</span>₄⁺] · [NH₂⁻] = x; equilibrium concentration of cations and anions.<span>
Kam = [NH</span>₄⁺] · [NH₂⁻].<span>
Kam = x².
x = [NH</span>₄⁺] = √5,1·10⁻²⁷.<span>
[NH</span>₄⁺] = 7,14·10⁻¹⁴<span> M.</span>

zzz [600]

Answer: all elements in the periodic table is classified as elements

Explanation:

The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with similar chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases
