Identify the following reaction as oxidation and reduction F2(g)+2e-/2F-(aq)

sertanlavr [38]

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.

which are correct formulas for ionic compounds? for those that are not correct, give the correct formula and justify your answer

skelet666 [1.2K]

Answer:

Ionic compounds have a metal and nonmetal.

Ionic compounds are made up of ions.

Explanation:

You did not provide any formulas for me to correct, but:

ionic compounds tend to have metals and nonmetals. (EX: NaCl)You can look at the periodic table to see which elements are metals and which are not.
ionic compounds are made up of ions. Ions are elements that have a charge (Like $Cu^{2+}$ or $O^{-}$ ). To have a correct ionic compound, make sure that the ions inside of it "cancel" each other out.

EX: Na has a +1 charge. Cl has a -1 charge. When they are paired up, they successfully cancel each other out (become neutral) and become the ionic compound NaCl.

The chart below shows you the charge of each element. Make sure the charge of the elements in an ionic compound "cancel" each other out.

The very last chart shows the metals and nonmetals
