An ionic equation refers to a chemical equation where the electrolytes in aqueous solution are demonstrated as dissociated ions. Generally, this is a salt dissolved in water, where the ionic species are succeeded by (aq) in the equation, to suggest that they are in aqueous solution.
Net ionic equation refers to a chemical equation for a reaction that lists only those species that takes part in the reaction. It is an equation, which demonstrates only the reactants taking part in the formation of a precipitate.
In the given case, balanced chemical equations is,
AgNO₃ (aq) + NaCl (aq) = AgCl (s) + NaNO₃ (aq)
Complete ionic equation:
Ag⁺ (aq) +NO₃⁻ (aq) + Na⁺ (aq) + Cl⁻ (aq) = AgCl (s) + Na⁺ (aq) + NO₃⁻ (aq)
Net Ionic equation:
Ag⁺ (aq) + Cl⁻ (aq) = AgCl (s) (Silver chloride settles as white precipitate)

The ions formed are NH4(+) and S(2-)
The dissolution reaction of (NH4) 2S in water is as follows:
(NH4) 2S ==> 2 NH4 (+) + S (2-).
Ammonium sulfide is the ammonium salt of hydrogen sulfide. It has the formula (NH4) 2S and belongs to the sulfide family.
It is a relatively unstable compound (crystals decomposing at -18 ° C, but exists and is more stable in aqueous solution.) With a pKa exceeding 15, the hydrosulfide ion cannot be significantly deprotonated by ammonia. Thus, such solutions consist mainly of a mixture of ammonia and hydrosulphide of ammonium, it has a smell, close to that of hydrogen sulfide, and its aqueous solutions can be precisely by emitting H2S.
Surface tension
..viscosity is the thickness of a liquid, doesn't fit here...condensation and evaporation are processes not properties.
First, we need to get the number of moles:
from the reaction equation when Y4+ takes 4 electrons and became Y, X loses 4 electrons and became X4+
∴ the number of moles n = 4
we are going to use this formula:
㏑K = n *F *E/RT
when K is the equilibrium constant = 4.98 x 10^-5
and F is Faraday's constant = 96500
and the constant R = 8.314
and T is the temperature in Kelvin = 298 K
and n is number of moles of electrons = 4
so, by substitution:
㏑4.98 x 10^-5 = 4*96500*E / 8.314*298
∴E = -0.064 V
