How do the properties of a compound like h2o or nacl illustrate the concept of emergent properties?
Softa [21]

Answer and explanation;

Na - metal

Cl - poisonous gas

NaCl - cyrstaline solid that is edible

An emergent property is a property which a collection or complex system has, but which the individual members do not.  

Water emergent properties: cohesion & adhesion, versatile solvent, temperature moderation, freezing.

The properties of a compound can be very different from the properties of the elements that make them, for example, Sodium is an explosive metal, and  Chlorine is a toxic gas, however, sodium chloride is a Delicious table salt!

Draw the product of the reaction between CH3CH=CHCH3 and H2 under a platinum catalyst.
Pani-rosa [81]

Answer:

CH₃CH₂-CH₂CH₃

Explanation:

When an alkene, R-CH=CH-R reacts with H₂ in a Pt catalyst, the analogue alkane, R-CH₂-CH₂-R, is produced (Hydrogenation of alkenes via Pt/Pd catalyst)

Thus, the reaction of CH₃CH=CHCH₃ with H₂ under a platinum catalyst produce:

<h3>CH₃CH₂-CH₂CH₃</h3>

The analogue alkane

What is the reason for the low solubility of LiF (0.27 g
Brut [27]

Answer:

The answer is C. The high solvation energy for LI+

Explanation:

LiF has lower solubility because of the high solvation energy of Li+ ion. This is due to the smaller  size and very big charge compared to Cs+ ion which has a bigger size and solvent molecules easily surround it.

Solvation energy is simply the amount energy that is required to make a solute dissolve in a solvent.
