Explanation:
The drug thalidomide with molecular formula C13H10N2O4 was widely prescribed by doctors for morning sickness in pregnant women in the 1960s.
The drug was sold as a racemic mixture (+)(R)-thalidomide and (-)(S)-thalidomide.
Unfortunately, only the (+)(R)-thalidomide exhibited the required effect while (-)(S)-thalidomide is a teratogen.
This goes a long way to underscore the importance of separation of enantiomers in drug production.
Therefore, all the teratogenic effects observed when using the drug thalidomide was actually as a result of the presence of (-)(S)-thalidomide, the unwanted enantiomer.

Answer:
Explanation:
The normal force is the support force exerted upon an object that is in contact with another stable object. The air resistance is a special type of frictional force that acts upon objects as they travel through the air. The force of air resistance is often observed to oppose the motion of an object.
B. is positive
H20 (l)--> H20 (g)
when that happens, the heat is absorbed into the liquid to change the state of the liquid to gas; therefore, in order to change to a gaseous state, heat must be a reactant. and so enthalpy is increasing
M(Li₃PO₄)=115.8 g/mol
c(Li⁺)=0.175 mol/L
v=500 mL= 0/5 L
n(Li⁺)=3n(Li₃PO₄)=3m(Li₃PO₄)/M(Li₃PO₄)=c(Li⁺)v
m(Li₃PO₄)=c(Li⁺)vM(Li₃PO₄)/3
m(Li₃PO₄)=0.175*0.5*115.8/3=3.3775* g
*Solubility lithium phosphate in water about 0,34 g/L. Litium phosphate can be dissolved in solution of a phosphoric acid. For example:
2Li₃PO₄(s) + H₃PO₄(aq) = 3Li₂HPO₄(aq)
