Find the molar mass of fe2o3. Then multiply 4.3 x molar mass of fe2o3/1 moles
The answer is E it’s killing all oxygen that is around you
It is a radio wave
Explanation:
The energy of an electromagnetic waves is related to its frequency by the equation:

where
h is the Planck constant
f is the frequency of the wave
We notice that the energy of an electromagnetic wave is proportional to its frequency. This means that waves with higher frequencies, such as gamma rays, x-rays, are more energetic, while waves with lower frequencies, such as microwave and radio waves, are the less energetic.
In this case, we want to find the frequency of a wave with energy
E = 0.000001 eV
Converting into Joules,

Solving for the frequency,

Which falls in the range of frequency of radio waves.
