Answer: It is non-spontaneous at all T.
Explanation:
According to Gibb's equation:
= Gibbs free energy = +ve
= enthalpy change = +ve
= entropy change = -ve
T = temperature in Kelvin
= +ve, reaction is non spontaneous
= -ve, reaction is spontaneous
= 0, reaction is in equilibrium
Putting in the values:
Reaction is non spontaneous at all temperatures.
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.
In one mole of talc, we observe that there are:
3 moles of Mg
4 moles of Si
2 moles of H
12 moles of O
The molar ratio of O to Mg is then:
12 moles of O : 3 moles of Mg = 4 : 1
Therefore, if 6.1 moles of Mg are present, the moles of O are:
4 * 6.1 = 24.4 moles of O

Answer:
Scientists have figured out that several genes are involved in skin color.
Explanation:
Parents can have children with skin color that is significantly lighter or darker than their own. Sometimes a particular gene can have a much bigger effect than other genes.
