<u><em>Answer:</em></u>
- The correct option is B. The nonpolar substance has a lower boiling point than the polar substance.
<u><em>Explanation: </em></u>
- Substances with hydrogen bonding, an intermolecular force, will have much higher boiling points than those that have ordinary dipole-dipole intramolecular forces. Non-polar molecules have lower boiling points, because they are held together by the weak van der Waals forces.
<em><u>Note</u></em>
- However, if size of non polar increases, then its boiling point increases due to increases in van der walls forces with large size.
About 8.0 moles of methane.Number of moles = MassMolar mass.
And thus we get the quotient:
128.3⋅g16.04⋅g⋅mol−1=8.0⋅moles of methane.
Note that the expression is dimensionally consistent, we wanted an answer in moles, and the quotients gives, 1mol−1=11mol=mol as required.
D.) It depends cuz no yeild is 100%..I mean side reactions also occur in most of the reactions. So mass of the reactant is not equal to the mass of the product. Hope it helps
