The answer is D. In the visible spectrum of light, ultraviolet light has the most energy while red has the least energy. Violet light has shorter wavelengths and higher frequency. This is converse to red light that has longer wavelengths but lower frequency.
If im not mistaken plant cells go through a stage called photosynthesis meaning the cells can create it's own energy (food) off of water, Co2 and sunlight.

Answer:
<u>2.13</u> moles of AlCl3 are produced from 3.2 moles of Cl2
Explanation:
Moles : The amount of substance that contain as many particles as present in 12 grams of C-12.
The balanced equation for the reaction is :

This reaction shows the following :
2 mole Al = 3 mole Cl2 = 2 mole AlCl3
In question we are asked to calculate the moles of AlCl3 produced from Cl2
So, we will use only Cl2 andAlCl3 moles
3 mole Cl2 = 2 mole AlCl3
1 moles of Cl2 will give =
of AlCl3
3.2 moles of Cl2 will give =
of AlCl3
= 2.133 moles
I would say that it is answer B because, it is found on earth because it is in a human and its not an abundant state of matter
