Solution : Water and Methanol are easily miscible in any amount. so they are not preferred for the liquid-liquid extraction process.
Liquid-Liquid Extraction is also called as solvent extraction. It is the method of seperation of compound based on their relative solubilities in two different immiscible liquids. Generally we use water (polar) and an organic solvent (non-polar).
It is important that the two solvents should not be mix because it is easy to seperate them.
Water and Methanol are easily miscible in any amount. we can not seperate them easily. So that is why we can not use water and methanol as a solvent in liquid-liquid extraction process.
Answer:
they could be joined due to hydrogen bridge-type intermolecular interactions so no phase splitting will be carried out.
Explanation:
Hello,
Liquid-liquid extraction is a widely used separation operation that is suitable when relative volatilities are so close, so an extra substance is used to modify the equilibrium causing a phase splitting (two liquid immiscible phases) which could be leveraged to mechanically separate the two phases. The basic idea lies on the fact that the extra substance must be largely immiscible with the original solvent, to the solute is selectively separated, nonetheless, in this case, water and methanol are largely soluble to each other since they could be joined due to hydrogen bridge-type intermolecular interactions so no phase splitting will be carried out.
Best regards.

3.6124 m/kg
Explanation:
Molality is calculated as moles of solute (mol) divided by kilogram of solvent (kg). Here, we can find these numbers by using the 35.4%, which gives us 35.4 g of H3PO4 and 100 g of solution to work with.
To go from grams to moles for the phosphoric acid, you need to find the molar mass of the compound or element and divide the grams of the compound or element by that molar mass.
Here, the molar mass for phosphoric acid is 97.9952 g/mol. The equation would look like this:
35.4 g x 1 mol / 97.9952 g = 0.3612422 mol
Next, the 100 g of solvent can easily be converted to 0.1 kg of solvent.
To find the molality, divide the moles of solute and kilograms of solution.
0.3612422 mol / 0.1 kg = 3.6124 m/kg

In contrast to inorganic chemical rocks, which result from non-biological processes such as salt left over when a lake evaporates, biochemical rocks are formed by once-living creatures, such as limestone from marine shells.
The process, which is inorganic and frequently the consequence of a body of water evaporating and concentrating the ions, occurs in chemical sedimentary rocks. The formation of one kind of sedimentary rock may be mediated by both chemical (inorganic) and biological (organic) processes. Aragonite and calcite make up limestone. The majority of limestone is biological in origin, while it can also occur as a chemical sedimentary rock that forms inorganically as a result of precipitation. In actuality, limestone is the biochemical sedimentary rock that is found most frequently. In marine (i.e., oceanic or salty sea) settings, nearly all limestone

Chromatography is a pretty accurate description of what happens to ink on wet paper, because it literally means "color writing" (from the Greek words chroma and graphe). Really, though, it's a bit of a misnomer because it often doesn't involve color, paper, ink, or writing. Chromatography is actually a way of separating out a mixture of chemicals, which are in gas or liquid form, by letting them creep slowly past another substance, which is typically a liquid or solid. So, with the ink and paper trick for example, we have a liquid (the ink) dissolved in water or another solvent creeping over the surface of a solid (the paper).
The essential thing about chromatography is that we have some mixture in one state of matter (something like a gas or liquid) moving over the surface of something else in another state of matter (a liquid or solid) that stays where it is. The moving substance is called the mobile phase and the substance that stays put is the stationary phase. As the mobile phase moves, it separates out into its components on the stationary phase. We can then identify them one by one.

Answer: Option (b) is the correct answer.
Explanation:
Reduction is defined as the process in which there occurs gain of hydrogen. Whereas oxidation is defined as the process in which there occurs loss of hydrogen.
As the given reaction is as follows.
Since, hydrogen is being added in this chemical reaction. It means that reduction is taking place and carbon atom is reduced.
Thus, we can conclude that in the given reaction carbon atoms are reduced.
