Question #dc82b
1 Answer
c.
Explanation:
We need to find the oxidation state of
a.
Fluorine's oxidation state can only be -1. However, there are two fluorine ions present, so their total charge equals -2.
Since compounds are always electrically neutral, the oxidation state of
b.
Since hydrogen has a higher electronegativity (2.2) than manganese (1.6), hydrogen's oxidation state is -1. However, there are 3 hydrogen ions present, so their total charge equals -3.
Since compounds are always electrically neutral, the oxidation state of
c.
The oxidation state is 0, since this an uncombined
d.
This one is a bit trickier. This is a polyatomic ion, so it has an overall charge of 1-.
We do know that the oxidation state of oxygen is almost always -2. However, there are 4 oxygen ions here, so the total charge is -8. Using this information, we can set up an equation to solve for the oxidation state of
The oxidation state of
So the answer is c.
