A should be the correct answer because any argument based on science makes a result more logical.
The answer is A) Aluminum Bromide
hope this helps :)
Answer: C. Electrons are lost.
Explanation:
- The oxidation reduction reaction is between oxidizing agent and reducing agent.
- The oxidizing agent gains electrons and reduction process occurs to it, while the reducing agent losses electrons and oxidation process occurs to it.
- oxidizing agent + ne → product <em>"reduction process, gain electrons"</em>
- reducing agent → product + ne<em> "oxidation process, loss electrons"</em>
- Thus, The right answer is: in the oxidation process, electrons are lost.
Answer:
[ Ga ] = 1.163 E-8 Kg/m³
Explanation:
- %wt = [(mass Ga)/(mass Si)]*100 = 5.0 E-7 %
⇒ 5.0 E-9 = m Ga/m Si
assuming: m Si = 100 g = 0.1 Kg
⇒ m Ga = (5.0 E-9)*(0.1 Kg) = 5 E-10 Kg
∴ density (δ) Si = 2.33 Kg/m³
⇒ Volume Si = (0.1 Kg)*(m³/2.33 Kg) = 0.043 m³
⇒ [ Ga ] = (5 E-10 Kg)/(0.043 m³) = 1.163 E-8 Kg/m³
⇒ [ Ga ] =

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.
