Answer:
Reduction
Explanation:
The oxidation reduction reactions are called redox reaction. These reactions are take place by gaining or losing the electrons and oxidation state of elements are changed.
Oxidation:
Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.
Reduction:
Reduction involve the gain of electron and oxidation number is decreased.
In given reaction fluorine gas gain two electron and form fluoride ions.
F₂(g) + 2e⁻ → 2F⁻(aq)
The given reaction is reduction because oxidation state is decreased from zero to -1.
I think the answer is -2 which is answer A
Answer:
Yea pretty much it's 3.49
Explanation:
<span>It is true that a sudden increase in both intensity and duration of physical exercise can result in injury. The body needs time to process any changes. Muscles need to build strength and flexibility gradually and the joints need time to acclimate to changes in pressure.</span>
Answer: ![[OH^-] =10^{-10.75}=1.778\times 10^{-11}M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%20%3D10%5E%7B-10.75%7D%3D1.778%5Ctimes%2010%5E%7B-11%7DM)
Explanation: pOH is defined as negative logarithm of hydroxide ions. More is the number of ![[OH^-]](https://tex.z-dn.net/?f=%5BOH%5E-%5D)
ions , lesser is the pOH and vice versa.
pH + pOH = 14
![10.75=-log[OH^-]](https://tex.z-dn.net/?f=10.75%3D-log%5BOH%5E-%5D)
![[OH^-] =10^{(-10.75)}=1.778\times 10^{-11}M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%20%3D10%5E%7B%28-10.75%29%7D%3D1.778%5Ctimes%2010%5E%7B-11%7DM)
