the cut pieces will have their own north and south pole
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: (2)react completely in the reaction
limiting reactant determines the number of moles in a chemical reaction
excess reactant is the reactant with an excess number of moles
Answer: 0.03798 kilograms
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number
of particles.
To calculate the moles, we use the equation:
1 mole of chlorine gas
weighs = 71 g
Thus 0.535 moles of chlorine gas
will weigh =
(1kg=1000g)
Thus there are 0.03798 kilograms in 12 L of chlorine gas.
