Polished metals have a metallic luster, which means that?

Chemistry

Metallic luster refers to the way light casts off of a mineral. Polished metals such as gold have a metallic luster, which makes them look bright and shiny, and reflect more light than other minerals. There are also minerals that have metallic luster, but are not shiny or reflect much light, which is called dull metallic luster. 

Metallic luster - bright, shiny
Dull metallic luster - not shiny

Arrange the following substances in order of increasing solubility of water. C6H14, C6H13Br, C6H13OH, C6H12(OH)2.
Juli2301 [7.4K]

Answer:

C6H14 < C6H13Br  < C6H13OH < C6H12(OH)2

Explanation:

Hello,

In this case, since the solubility in water is related with the presence of polar bonds in the given molecules we can see that C6H12(OH)2 has the presence two O-H bonds which promote the highest solubility via hydrogen bonds as well as the C6H13OH but in a lower degree as only on O-H bond is present. Next since the bond C-Br in is slightly close to the polar bond C6H13Br rather than the C-C bonds only had by C6H14 we can infer that C6H13Br is more soluble in water than C6H14, therefore the required order is:

C6H14 < C6H13Br  < C6H13OH < C6H12(OH)2

Whereas C6H12(OH)2 is the most soluble and C6H14 the least soluble in water.

Best regards.

How does octect law work?
zlopas [31]
Octet law states that every atom tries to attain a octet valence shell (8 electrons in their valence shell) to attain a more stable state. For attaining this they form bonds(covalent,ionic etc) with other atoms. Please ask if you any more doubt on this, I'll try to help

How many moles of trifluoromethanoic acid (CHF3O3S) are present in 9.0345 × 1024 molecules of (CHF3O3S)?
timama [110]
1 mole ------------ 6.02x10²³ molecules
? moles ----------- 9.0345x10²⁴ molecules

( 9.0345x10²⁴) x 1 / 6.02x10²³ =

9.0345x10²⁴ / 6.02x10²³ => 15.007 moles

Why chemically did the prescribing of thalidomide for morning sickness in pregnant women lead to tragic consequences, including
Dominik [7]

Answer:

See explanation

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.
