Answer : The [α] for the solution is, -118.8
Explanation :
Enantiomeric excess : It is defined as the difference between the percentage major enantiomer and the percentage minor enantiomer.
Mathematically,
Given:
% major enantiomer = 86 %
% minor enantiomer = 14 %
Putting values in above equation, we get:
Now we have to calculate the [α] for the solution.
Thus, the [α] for the solution is, -118.8

Explanation:
Transition metals occupy the d block of the periodic table. Their location is right between the group 2A and 3A. Copper (Cu) is in the first row of the d-block elements. The image attached illustrates the position of the transition metals relative to other elements in the periodic table.
Answe 174.0 KPA
Explanation:
0°C in 101.3 K PA pressure a sample of gas occupies 30 mL if the temperature is increased to 30°C in the entire gas sample is transferred to a 20 mL container what will be the gas pressure inside a container
PV=nRTt
so
n = PV/RT
P = 101.3 KPA
T = 0+273.2 = 273.200
V = (30/1000) L = 0.03 L
R =0.082
SO
n= (101.3 X 0.03)/(0.082 X 273.2)
= 0.14 moles
PV= nRT
N= 0,14
T = 30 + 273.2= 303.2
V= (20/1000)L =0.02L
since PV = nRT
THEN
P=nRT/V
so
P=(0.14 X 0.082 X 303.2)/0.02 =
174.0 KPA
