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.

No, there are only 2 states that award electoral votes as a percentage of the popular vote. Nebraska and Maine award electoral votes based on which candidate won each Congressional district. The other 48 states are winner takes all.
EEG stands for Electroencephalogram. EEG measures electrical activity in the head related to the firing of a specific group of neurons reveals brain wave activity
When brief periods of EEG patterns are recorded in response to a specific event, the response is called an event-related potential or an evoked potential.
<span>This measure the electrical activity of the brain in response to a certain event stimulation.</span>
Answer:
Observational learning
Explanation:
Observation learning is social learning that occurs through the observation of the behaviour of others. It has various forms and is dependent on various processes. It requires a parent, friend , sibling or teacher to be a social model, someone who is elder and has higher status in the environment. Children learn to smoke, smack and swear from others through observation. They keep learning the desirable and undesirable behaviour through observational learning. Observational learning is also seen in animals. Animal obtain the instinctive behaviour by observing other animals.
