Answer:
Explanation:
The stereochemical structures of the two compounds of the fumarase-catalyzed reaction are in the attachment below. The reaction been referred to is illustrated in the equation below
HOOCCH=CHCOOH + H₂O ==> HOOCCH₂CH(OH)COOH
The compounds attached are trans-2-butenedioate (which is one of the reactants) and (s)-2-hydroxysuccinate (which is the product formed)
Note that stereoisomers are isomers that differ in spatial orientation, thus there are other isomers that could contain the same atoms and have slightly but different spatial orientation such as cis-2-butenedioate and (r)-2-hydroxysuccinate
Answer: 3) 39.96 amu
Explanation:
Mass of isotope Ar- 36 = 35.97 amu
% abundance of isotope Ar- 36= 0.337% =
Mass of isotope Ar- 38 = 37.96 amu
% abundance of isotope 2 = 0.063 % =
Mass of isotope Ar- 40 = 39.96 amu
% abundance of isotope 2 = 99.600 % =
Formula used for average atomic mass of an element :
Therefore, the average atomic mass of argon is 39.96 amu
