Answer:
He
Explanation:
From Graham's law of diffusion, lighter or less dense gas tends to diffuse faster than denser gas amongst the list, He is the lightest gas and so will diffuse faster
1.6 X M is the [H] in a HC102 solution that has a pH of 3.78.
Explanation:
Given:
pH of the acid = 3.78
[H+] ion concentration = ?
The dissociation of the acid is shown as:
+ ⇔ HClO2
however, weak acid like HClO2 does not dissociate or ionize completely which causes low hydrogen ion release in the solution.
pH is calculated by applying the formula:
pH = - log [H+]
To calculate the H+ ion concentration the equation will be expressed as:
[H+] =
=
= 1.6 X M
The concentration or molarity of the Hydrogen ion in the solution of the acid is 1.6 X M.

Answer:
8.5 mol H₂SO₄
Explanation:
It seems the balanced reaction the problem is referring to is absent, however the description matches the following balanced reaction:
- 2SO₂ + O₂ + 2H₂O → 2H₂SO₄
Now we <u>can convert 8.5 moles of SO₂ into moles of H₂SO₄</u>, using <em>the stoichiometric coefficients of the balanced reaction</em>:
- 8.5 mol SO₂ * = 8.5 mol H₂SO₄
