Answer:
Enantiomers
Chiral
Yes they will be formed in equal amount.
Explanation:
The Two possible stereo isomers are formed due to generation a chiral center in the molecule.
There will be a carbon with all the four groups different.
The two isomers will be called as enantiomers, which are non super-imposable mirror image of each other.
They are named as "R" or "S'" based on the selection rule.
The IUPAC names are also given in the figure.
The two isomers will be formed in equal amount as during photochemical chloriantion of a compound free radicals are generated (which are trigonal planar) and the other radical may attack from either side (front side or back side) giving the two stereo-isomers.
First let us compute for the number of moles of butane
(molar mass = 58.12 g/mol)
number of moles = 145 g / (58.12 g/mol) = 2.49 mol
<span>We use the ideal
gas equation to calculate the volume:</span>
<span> V = n R T / P</span>
V = 2.49 mol * 62.36367 L torr / mol K * 308.15 K / 745
torr
<span>V = 64.35 L</span>
I think the correct answer would be the last option. The statement that would best explain the derivation of the modern periodic table would be that it was made from much scientific examination, investigation, and argumentation of data by many scientists. It was indeed finalized by Mendeleev however his works are based on the works of previous scientists who focused on the elements in the periodic table. So, it was not solely a product of effort of only one scientist but rather a number of scientists. Without the the previous researches, Mendeleev would not be able to come to the modern periodic table.
Answer:
a pure substance and an element
Explanation:
A drop of liquid mercury be described as a pure substance and an element.
Mercury is one of the known elements in the periodic table. The drop of liquid mercury is pure since it has constant and definite composition as well as distinct chemical properties.
