Choose the pair of substances that are most likely to form a homogeneous solution. A) KI and HgB) LiCl and C6H14C) C3H8 and C2H5OHD) F2 and PF3E) NH3 and CH3OH

The answer is NH3 and CH3OH

Explanation:

The basic rule of a reaction is "like dissolves like" and for a homogenous mixture to form, there must be some common properties related to bonding.

1. KI and Hg

Normally mercury tends to form amalgam which is not a homogeneous solution.

2. LICL and C6H14

One is non polar and other is polar which makes the homogeneous reaction not possible.

3. C3H8 and C2H5OH

Both are miscible but will not develop homogeneous solution as propane is gas at normal temperature.

4. F2 and PF3

Flourine is highly electronegative and will repel fellow flourine making it not possible for homogeneous solution

5. NH3 and CH3OH

Both have same type of bonding and can react homogeneously.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
