Yes, toluene/water combination would be a good binary solvent system for a mixed recrystallization.
Because toluene is a fairly nonpolar chemical and water is polar, they will not dissolve together, making the combination of toluene and water an excellent binary solvent system.
<h3>What is mixed recrystallization?</h3>
- The substance to be crystallized is first dissolved in the smallest quantity of hot "soluble solvent," and then hot "insoluble solvent" is added dropwise until the solution becomes faintly hazy.
- This is how mixed recrystallization happens.
<h3>What is binary solvent?</h3>
- When synthesizing pharmaceuticals and drug precursors, binary solvent mixtures are employed as carriers in HPLC columns.
- For accurate and effective separation of the necessary pharmaceutical components, it is essential to precisely manage the mixture's composition.
- Water-based solutions of ethanol, sugar, and salt.

Answer:
The institution Rachels quotes to establish his claim that active euthanasia has been generally seen as immoral, while passive euthanasia is seen as acceptable is The American Medical Association.
Explanation:
In his "Active and Passive Euthanasia", James Rachels discusses the morality behind each of the concepts. In active euthanasia, someone would have to administer some sort of lethal drug for the patient to die, while in passive euthanasia, death happens by omission, by doing nothing and simply allowing someone to die. The American Medical Association considers active euthanasia "incompatible with the physician’s role as healer". It is the association's beliefe that, even if the patient does wish to die due to prolonged suffering and pain, euthanasia does "more harm than good".
The social pyramid in ancient Egypt was rigid because there was little chance to move up to a higher class. Hope this helped
