The functional group of aspartic acid is -COOH.
I think the correct answer is B. J.J. Thompson's Plum Pudding model had to be revised because atoms have protons and neutrons in the nucleus. He realized that aside from the electrons which are negatively charged, positive charge particles should be present to neutralize the charge of an atom.
<u>Given:</u><u> </u>
Mass of Nitrogen (N₂) gas = 75 grams
<u>Finding the number of moles of N₂:</u><u> </u>
We know that the molar mass of N₂ is 28 grams/mole
Number of moles = Given mass / Molar mass
Number of moles = 75 / 28
Number of moles = 2.68 moles
Hence, there are 2.68 moles in 75 grams of Nitrogen Gas
The answer is d on brainly
