Use n1/V1 = n2/V2
.1/2 = .4/V2
.1V2 = .8
V2 = 8 L or D
Molecule
The smallest unit in a compound is its molecule.
Answer:
Option B
Explanation:
As Brønsted-Lowry theory states, acids are the ones that can donate protons.
When a proton is donated, it is released to become medium more acidic.
HCl is a strong acid.
HCl (l) + H₂O (l) → H₃O⁺ (aq) + Cl⁻(aq)
These always reffers to strong acid where the dissociation is 100% completed.
In a weak acid, dissociation is not 100% complete, that's why we have an equilibrium.
HA (l) + H₂O (l) ⇄ H₃O⁺ (aq) + A⁻(aq) Ka
10 seconds = 8grams
then just divide by 2 another 4 times...
= 0.5grams after 50 seconds
