He, because it’s a noble gas which they have full valence electrons (occupied energy levels)
Answer: Chlorophyll is a green photosynthetic pigment found in plants, algae, and cyanobacteria.
Chlorophyll absorbs mostly in the blue and to a lesser extent red portions of the electromagnetic spectrum, hence its intense green color.
Green substance in producers that traps light energy from the sun, which is then used to combine carbon dioxide and water into sugars in the process of photosynthesis Chlorophyll is vital for photosynthesis, which helps plants get energy from light.
Chlorophyll molecules are specifically arranged in and around pigment protein complexes called photosystems, which are embedded in the thylakoid membranes of chloroplasts.

Answer:
was the concentration of the original solution.
Explanation:
(Dilution)
where,
are molarity and volume of non diluted sample.
are molarity and volume of diluted sample.
(1μL=0.001 mL)
Substituting all values :
was the concentration of the original solution.
No of moles of fe2o3 = 16.5/(55.8x2+16x3)=0.103mols
No. Of moles of iron= 0.103 x 2 = 0.206mols
Mass of iron = 0.206 x 55.8 = 11.5g
