Answer:
<u>Oxidation state of Mn = +4</u>
Explanation:
Atomic mass of Mn = 55g/mol
From Faraday's law of electrolysis,
Electrochemical equivalent = 
i.e Z =
=
= 0.0001424 g/C
But Equivalent weight, E = atomic mass ÷ valency = Z × 96,485
⇒
= 0.0001424 × 96,485
<u>∴ Valency of Mn = +4</u>
I believe it’s D because phosphorus has the mass of 30.9.
A. deposition
this means that it was moved from one place to another and can be transported by ice, water, gravity, or wind.
With the info given i would have to say their is no kinetic energy, it's all potential energy.
