Answer:
Distribution coefficient: 4.79
Explanation:
Distribution coefficient is the ratio between equilibrium concentration of non-aqueous phase and aqueous phase where both solvents are inmiscible. The equation for the problem is:
Distribution coefficient: Concentration in chloroform / Concentration in Water
<em>Concentration in water: 2.59mg / 30mL = 0.08633mg/mL</em>
<em>Concentration in chloroform: (15mg-2.59mg) / 30mL = 0.4137mg/mL</em>
<em />
Distribution coefficient: 0.4137mg/mL / 0.08633mg/mL
<h3>Distribution coefficient: 4.79</h3>
Answer:
<u>2-chlorohexane</u>
Explanation:
<u>In this figure</u> :
- There are 6 carbon atoms
- The Cl atom is bonded to the 2nd carbon atom
⇒ The Cl is a substituent group, termed as -chloro
⇒ Based on IUPAC nomenclature, the 6 atom chain starts with hex
⇒ There are only single bonds present, so it is an alkane
<u>The name is</u> :
Answer:
dear jesus i need glasses
Explanation:
Valence électrons don’t define which group You are in so you can cross those choices out.
A would be incorrect because element 1 has 1 valence electron while element 2 has 2 valence electrons.
D would be correct because both elements have two valence electrons.
Also, pls don’t hate if I am wrong!
