Answer:
The oil and water will separate. The oil will float to the top.
Explanation:
Answer:
( a ) soluble
( b ) soluble
( c ) insoluble
Explanation:
Solubility is determined by the principle , "like dissolves like" .
i.e. ,<u> if a compound is polar then it will dissolve in a polar compound only , </u>and
<u>if a compound is non - polar then it will dissolve in a non - polar compound only .</u>
Hence , from the question ,
( a )
Methanol and water as we know are both polar species , hence , according to the principle - soluble .
( b )
Hexane and cyclohexane
Both the species are polar species , hence , according to the principle - soluble .
( c )
Hexane and water
In this case ,
Hexane , is non polar and water is polar , hence , the mixture will be non soluble .
The electronic geometry for the carbonate ion, in CO₃²⁻ is trigonal planar, and molecular geometry will be trigonal planar.
The electronic geometry = Total number of atoms + lone pair around the central atom
= 3 atoms + 0 lone pair
= sp₂ (trigonal planar)
The molecular geometry = As there is no lone pair its geometry will be trigonal planar.
