32 grams of sulfur will contain 6.022 X 1023 sulfur atoms.
The original radioisotope underwent double-alpha decay, where the original nucleus lost a total of 4 protons and 4 neutrons.
The original radioisotope would have an atomic number of 86+4 (protons), and would have an atomic mass of 222+8 (protons + neutrons). This would make the element Thorium-230, or 90Th230.
Answer:The atomic weight is the lower number on each chemical. Fe has a mass of 56, S a mass of 32 and O a mass of 16. As there are four oxygens present in this compound, you multiply 16 by 4 to get 64. Lastly you add all these separate masses together, which gives a total relative mass of 152.

The unique identity of amino acid is that each amino acid is bonded to each central atom known as R-group.
Explanation:
Amino acids are nothing but a basic structure which has a central atom called the "alpha carbon atom". This 
carbon atom is bonded to an "amino group" (
), a "carboxyl group" (COOH) or a "hydrogen atom".
There are totally "20 types" of amino acids having a central atom bonded from the R-group. For example: When the R-group is hydrogen, then the amino acid is named glycine. Similarly, if it is attached to methyl group, then the amino acid is alanine. This makes the amino acids unique.
