Question

Can someone explain this to me Pic below

Answer 1

In the given equilibrium reaction:

F
−
(
𝑎
𝑞
)
+
H
2
O
⇌
HF
(
𝑎
𝑞
)
+
OH
−
(
𝑎
𝑞
)
F
−
(aq)+H
2

O⇌HF(aq)+OH
−
(aq)

If water is acting as an acid, it means that it is donating a proton (H
+
+
) to another species. In this case, water is donating a proton to the fluoride ion (F
−
−
).

Therefore, the correct answer is:

B. The water donates H
+
+
to F
−
−
.

Answer 2

Idk y it did tht

Answer 3

No not from google. My friends text

Answer 4

One thing you should take notice of is the charges on the elements as it transitions from one side to the other.

The fluorine (\(\color{red}{F} \)) goes from \(\color{red}{-1} \) to a neutral charge of \(\color{green}{0} \), meaning it gained a proton. In this case, it gained a hydrogen ion (aka a proton).
The water, which was acting as an acid, lost a proton going from \(\color{green}{0} \) to \(\color{red}{-1} \).

So you can conclude that the water molecule donated a proton/hydrogen \( H^+ \) to the ion Florine \( F^- \)
