🤓 Based on our data, we think this question is relevant for Professor Kennedy's class at GSU.

Solution: Choose the pair of substances that are most likely to form a homogeneous solution.a. C6H14 and C10H20b. LiBr and C5H12c. N2O4 and NH4Cld. C6H14 and H2Oe. None of these pairs will form a homogeneous solution.

Problem

Choose the pair of substances that are most likely to form a homogeneous solution.

a. C6H14 and C10H20

b. LiBr and C5H12

c. N2O4 and NH4Cl

d. C6H14 and H2O

e. None of these pairs will form a homogeneous solution.

Solution

We’re being asked to determine which among the given pair of substances is most likely to form a homogenous solution.


Homogenous solution 

mixed together as evenly as possible
the components of the solution are indistinguishable


We’re going to use the theory “likes” dissolving “likes”  which states that the solvent can only completely dissolve the solute if they share similar polarity

Therefore, a pure solvent with similar polarity can successfully dissolve a solute to create a solution. 


Let take a look at each option given:

a. C6H14 and C10H20
