Answer:
Explanation:
Option A is correct .. reactants bond breaks and form new bonds to form product
HClO4(aq) ===> H+(aq) + ClO4-(aq)
If [HClO4] = 0.175 M, then [H+] = [ClO4-] = 0.175 M
[OH-] = 0.175 M = 1.75 x 10^-1 M
Kw = [H+][OH-} = 1.00 x 10^-14 [OH-] = 1.00x10^-4/1.75x10^-1 = 5.71 x 10^-14 M
1. friction that’s all i know lol
Answer is: concentration of hydrogen iodide is 6 M.
Balanced chemical reaction: H₂(g) + I₂(g) ⇄ 2HI(g).
[H₂] = 0.04 M; equilibrium concentration of hydrogen.
[I₂] = 0.009 M; equilibrium concentration of iodine.
Keq = 1·10⁵.
Keq = [HI]² / [H₂]·[I₂].
[HI]² = [H₂]·[I₂]·Keq.
[HI]² = 0.04 M · 0.009 M · 1·10⁵.
[HI]² = 36 M².
[HI] = √36 M².
[HI] = 6 M.
