Answer:
Explanation:
NaCl dissolves in water but not in benzene because the water-ion interactions are stronger than benzene-ion interactions.
This statement is true . NaCl is ionic compound . I water is ionises strongly because of strong ion - water interaction . It does not dissolve in benzene because of low ion - benzene interaction .
NaCl dissolves in water but not in hexane because the enthalpy of mixing NaCl with water is more negative than that of mixing NaCl with hexane.
This statement is wrong because enthalpy of mixing NaCl with water is positive and not negative .
NaCl dissolves in water but not in benzene(C6H6) because there are no hydrogen bonds in benzene.
This statement is wrong . NaCl does not make hydrogen bond with water molecule .
Electron donors are bases while electron acceptors are acidic. Electron donors will often have a negative charge and a lone pair to donate. Electron acceptors are usually very electronegative atoms such as chlorine
The mole fraction of NaCl in a mixture : 0.195
<h3>Further explanation</h3>
The mole fraction shows the mole ratio of the compound to the moles of the mixture/solution
Can be formulated :
n tot = n₁+n₂+....nₙ
a mixture of 0.564 g NaCl,
1.52 g KCI, and 0.857 g LiCl
- mol NaCl (MW=58.44 g/mol)
mol LiCl(MW=42,394 g/mol)
n total =
the mole fraction of NaCl :
