So so confused uh jus listen to the other answer aha
Answer:
Explanation:
To isolate a single variable when rearranging equations, move all other variables to the other side of the equation by using its inverse operation on them and remembering to perform that operation on itself. Make sure the rearrangement has the target variable. For example, we can grab a simple equation such as the one below and isolate x.
x - 5y + 3 = 25 ... first we subtract 3 from both sides
x - 5y = 22 ... now we add 5y to both sides which will cancel out the 5y on the left
x = 22 + 5y
And we finally have the x variable isolated.
Answer:
H₂SO₄ (aq) + H₂O (l) → HSO₄⁻ (aq) + H₃O⁺ (aq)
HSO₄⁻ (aq) + H₂O (l) ⇄ SO₄⁻²(aq) + H₃O⁺ (aq) Ka
Explanation:
The sulfuric acid is a dyprotic acid.
It is a considered a strong acid but only the first deprotonation is strong.
Second deprotonation is totally weak
That's why we have equilibrium when it release the second proton.
Since a deprotonation is treated for a weak acid, the acid is considered not to completely dissociate, that's why the equilibrium
