Answer:
What do you mean what happened?
Explanation:
???
The oxidation state of Hydrogen in reactant side is 0 and that in product side is +1. Hence the reaction is oxidation.
Answer:
Molecular Formula = C6H6
Explanation:
Empirical Formular = CH
Molar Mass = 78.11
Molecular Formular = ?
The Formular relating these parameters is given as;
(Empirical Formula)n = Molecular Formular
where n = Number of moles
CH = 12.0107 + 1.00784 = 13.01854
(13.01854)n = 78.11
n = 78.11 / 13.01854
n = 5.9999 ≈ 6
Molecular Formula = C6H6
The lithium ion[Li⁺]=1.642 M
<h3>Further explanation</h3>
Ionic compounds will dissociate into ions when dissolved in water. The strength of the dissociation depends on the strength of the electrolyte properties. The stronger it is, the more ions will dissociate
Reaction
Li₂S⇒2Li⁺+S²⁻
mol ratio Li₂S : Li⁺: S²⁻ = 1 : 2 : 1
so the lithium-ion (Li⁺) concentration :
Answer:
pH = 2.0
Explanation:
the pH of the strong HCl acid solution will be
pH = -log[H+] = -log[0.010] = 2
