Answer:
If i had to take a stab at it would say C
Explanation:
C1V1 = C2V2
4 L x 0.5 mole/L = 4 L x C
2 mole = 4 C
.: final concentration = 0.5 mole / L
Answer:
1) n-Hexane. 2) 2-Methyl pentane(IUPAC name) or Isohexane(common name). 3) 2,2-Dimethylbutane(IUPAC name) or Neohexane(common name). 4) 3-Methylpentane
Explanation:
The reduction is solubility is because 3) of a common ion effect.
The common ion effect is when an ion that is already present in a solution is added, causing the following equilibrium to be disturbed:
AB ↔ [A+] + [B-]
If [B-] is added, then according to Le Chatelier's principle, the equilibrium must shift backward, creating more undissolved precipitate.<span />
