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!
Patent - Not sure if this is much of a Chem question dou.
I think that it would be 12
Answer: 2.3 moles
Explanation:
Recall that based on Avogadro's law, 1 mole of any substance has 6.02 x 10^23 atoms
So if 1 mole of Aluminum = 6.02 x 10^23 atoms
Then, Z moles = 1.4 x 10^24 atoms
To get the value of Z, we cross multiply:
1 mole x 1.4 x 10^24 atoms = Z x (6.02 x 10^23 atoms)
1.4 x 10^24 atoms = Z x (6.02 x 10^23)
Hence, Z = (1.4 x 10^24 atoms) ➗ (6.02 x 10^23 atoms)
Z =2.3 moles
Thus, there are 2.3 moles in 1.4 x 10^24 atoms of aluminum.
