Answer:
1.125 x 10⁻³.
Explanation:
- For the reaction: <em>2NO(g) + Cl₂(g) → 2NOCl(g).</em>
<em>Kc = [NOCl]²/[NO]²[Cl₂],</em>
Where, [NOCl], [NO], and [Cl₂] is the equilibrium concentration of NOCl, NO, and Cl₂.
∵ Initial concentration of NO and Cl₂ = 0.50 M.
<em>And the equilibrium concentration of NOCl = 0.30 M.</em>
<em />
∴ The equilibrium concentration of NO, and Cl₂: [NO] = [Cl₂] = 0.50 M - 0.30 M = 0.20 M.
<em>∴ Kc = [NOCl]²/[NO]²[Cl₂]</em> = [0.30]²/[0.20]²[0.20] = <em>1.125 x 10⁻³.</em>
Explanation:
White precipitate of silver chloride get dissolves in excess ammonia to formation of complex between silver ions, chloride ions and ammonia molecules.
The chemical reaction is given as:
![AgCl(s)+2NH_3(aq)\rightarrow Ag[(NH_3)_2]^+Cl^-(aq)](https://tex.z-dn.net/?f=AgCl%28s%29%2B2NH_3%28aq%29%5Crightarrow%20Ag%5B%28NH_3%29_2%5D%5E%2BCl%5E-%28aq%29)
When 1 mole of silver chloride is added to 2 mole of an aqueous ammonia it form coordination complex of diaaminesilver(I) chloride.
Answer:
The tendency for water molecules to stick together causes it to causes spheres in space. ... Magnetic-like molecules on water's surface cause the surface to behave like an elastic skin. Each molecule is pulled with equal tension by its neighbors.J
