Oil doesn't dissolve in water, which could be your answer.
The answer is dipole-dipole and dipole-induced dipole forces.
The dipole-induced dipole is a kind of interaction induced by a polar molecule by disturbing the arrangement of electrons.
- In methyl cyclohexanone molecules, there is a permanent dipole moment due to dipole moment vectors not canceling.
- There is induction of dipole by disturbing the electronic arrangement.
- A permanent dipole moment is created in this interaction.
- Dipole-dipole interactions are defined as the forces that is formed from the close linkage of permanent or induced dipoles.
- These forces are called Van der Waal forces.
- Proteins contain a large number of these interactions, which vary considerably in strength.

The thermal energy needed to completely melt 9.60 mole of ice at 0.0 C is 57.8 Kj
Explanation
ice melt to form water
The molar heat of fusion for water is 6.02 Kj/mol
Thermal energy = moles x molar heat of fussion for water
=9.6 mol x6.02 kj/mol =57.8 Kj
The correct answer for the question that is being presented above is this one: "<span>0.3."
Here it is how to solve.
M</span><span>olecular mass of Ar = 40
</span><span>Molecular mass of Ne = 20
</span><span>Number of moles of Ar = 9.59/40 = 0.239
</span><span>Number of moles of Ne = 11.12/20= 0.556
</span><span>Mole fraction of argon = 0.239/ ( 0.239 + 0.556) = 0.3</span><span>
</span>
Answer: A. To change the potential energy of the reactants.
Explanation:
Catalysts make such a breaking and rebuilding happen more efficiently. They do this by lowering the activation energy for the chemical reaction. Activation energy is the amount of energy needed to allow the chemical reaction to occur. The catalyst just changes the path to the new chemical partnership.
