Answer:
2 hydrogen and 1 oxygen atoms
Explanation:
First we will calculate the number of moles of Iron:

, where n is the number of moles, m is the mass of iron in the reaction and M is the Atomic weight.

moles of Iron.
The same number of moles of Oxygen will take part in the reaction.
So

where 32 is the Atomical Weight of Oxygen (16 x 2).
=>

g
Answer:

Answer:
Another name for light is ¨Electromagnetic Radiation, luminous energy, and/or radiant energy.¨
Explanation:
Light is the electromagnetic radiation that´s capable of causing a visual sensation and has wavelengths from about 380 to about 780 nanometres. Electromagnetic radiation includes Radio Waves, Microwaves <u>(used in microwaves)</u>, Infrared Radiation <u>(heat)</u>, Visible Light <u>(the colors we see)</u>, Ultraviolet <u>(the UV radiation that causes sunburns)</u>, X-Rays <u>(used in medical X-Rays)</u>, and Gamma Rays <u>(which can be used to treat cancer)</u>. Light waves are transverse waves because they only travel east or west, but their crests and troughs face north and south (if desplayed on a coordinate grid). They wouldn´t be longitudinal waves because these waves don´t have vertical crests and troughs.
I hope this helps!
