An unknown clear liquid solvent is tested for identification in the lab using
solubility tests. The unknown solvent is either methanol (CH3OH), methane
(CH4), or pentane (C5H12). The unknown liquid is mixed with the following
solutes, NaCl, H20 and C2H6. The solutes that are soluble in the unknown
solvent are NaCl and H20. What is the identification of the solvent?
Methane
Pentane
None are possible
Methanol

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
