The general rule for dissolving states that "like dissolves like," meaning polar solvents tend to dissolve polar solutes, while nonpolar solvents dissolve nonpolar solutes.
In this context:
- A. Oil and water do not mix. (correct)
- B. Oil and water mix. (incorrect, as they do not mix)
- C. Water and methanol mix. (correct, both are polar)
- D. Methanol and oil do not mix. (correct, as methanol is polar and oil is nonpolar)
- E. Oil and grease mix. (correct, as both are nonpolar)
The item that is NOT consistent with the general rule for dissolving is **B. Oil and water mix.**
