I got this stupid question wrong so that you people don't have to. I simply hate chemistry and I wish it didn't exist. Kind of like this website that makes me explain the answer.
Trust me, the answer is correct
The primary element that makes steel stainless is Chromium (Cr)
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.
Answer:
6.1 ×10^-19 J
Explanation:
From E= hc/λ
h= planks constant = 6.6×10^-34 Js
c= speed of light = 3×10^8 ms^1
λ= wavelength = 325 nm
E= 6.6 × 10^-34 × 3×10^8/325 × 10^-9
E= 0.061 × 10^ -17 J
E= 6.1 ×10^-19 J
