Answer:
Explanation:
idk why all u guys like trump who do.. hes just a big pain in the a*s.
L- isomer is considered as the Enantiomer of d- isomer and since the d-isomer optical rotation is + 13.5° so the optical rotation of l-isomer will be the same degree but with opposite sign which equal to -13.5°
So the degree of rotation of racemic mixture will equal 0°
- This is because racemic mixture contains equal amount of both enantiomers
(2) argon. This is because Ca originally has 20 total electrons with a configuration of 2,8,8,2. When it looses its valence electrons it remains with 18 electrons total (2,8,8 config). Argon has 18 electrons total too (2,8,8 config).
Answer:
12.78 kJ
Explanation:
The correct balanced reaction would be

Mass of methanol = 
Moles of methanol can be obtained by dividing the mass of methanol with its molar mass 

Enthalpy change for the number of moles is given by


The change in enthalpy is 12.78 kJ.
