The correct answer is A
Filter out the sand, because the sand does not dissolve in water, and then evaporate water from sugar solution

Answer:

Option A) filter the sand

Explanation:

When mixing sand and sugar with water, the sand stands in suspention and the sugar disolves because of its high solubility in water.

You can't filter  out the sugar with traditional methods, and if you use for example reverse osmosis you will have water in one side and still a mixture of sand and sugar in the other. So option B) is not possible

If wait for both componets to settle down, that may never happen. The sugar will remain in solution. So option C) is discarded  

Using a magnet has no effect because both elements are non-ferrous, so option D) is also discarded.

At last, you can filter the sand like option A), then evaporate the water from the solution with the sugar and you will have sugar and sand separated.

How might a scientist compare theories by doing an experiment?
Degger [83]

The scientist could B) do an experiment to that would apply to only one of the theories.

If the results agreed with that theory, it would <em>become more acceptable</em>.

If the results disagreed with that theory, it would be <em>disproved</em> and the other theory would become more acceptable.

At 298 K the standard enthalpy of combustion of sucrose is -5645 kJ/mol and the standard reaction Gibbs energy is -5798 kJ/mol.
natka813 [3]

Explanation:

The given data is as follows.

             T = 298 K,          \Delta H^{o} = -5645 kJ/mol

          \Delta G^{o} = -5798 kJ/mol

Relation between \Delta H and \Delta G are as follows.

          \Delta G^{o} = \Delta H^{o} - T \Delta S^{o}    

             -5798 kJ/mol = -5645 kJ/mol - 298 \times \Delta S^{o}

                       -153 kJ/mol = -298 \times \Delta S^{o}

                    \Delta S^{o} = 0.513 kJ/mol K

Now, temperature is 37^{o}C = (37 + 273) K = 310 K

Since,        \Delta G = \Delta H^{o} - T \Delta S^{o}

                            = -5645 kJ/mol - 310 K \times 0.513 kJ/mol K

                            = (-5645 kJ/mol - 159.03 kJ/mol)

                            = -5804.03 kJ/mol

As, change in Gibb's free energy = maximum non-expansion work

            \Delta G = \Delta G_{310 K} - \Delta G_{298 K}

                           = -5804.03 kJ/mol - (-5798 kJ/mol)

                           = -6.03 kJ/mol

Therefore, we can conclude that the additional non-expansion work is -6.03 kJ/mol.
