Explanation:
It is known that molecular formula of potassium dichromate is
. As potassium has an oxidation state of +1 and an oxygen atom has an oxidation state of -2.
Let the oxidation state of chromium is x. Therefore, calculate the oxidation state of chromium as follows.
= 0 (as the molecule is neutral)
= 0
2 + 2x - 14 = 0
x = +6
Thus, we can conclude that the oxidation state of the chromium in the potassium dichromate molecule is +6.
Answer:
When Sedimentary rocks are buried deep beneath the Earth's surface, great pressure and tremendous heat change these rocks into new rocks containing different minerals. These are Metamorphic rocks.
