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.
C6H12O6 + 6 O2 --> 6 CO2 + 6 H2O
Atomic number = No. of proton = 1
so, your answer is 1
Scientific evidence does not always agree because not all scientific evidence is the same.
by melting and boiling points. Certain metals have a constant and same boiling and melting point.
