What purpose does a 1 cm layer of anhydrous sodium sulfate in the apex of the funnel serve while transferring the dichloromethane extract into the round-bottom flask?

Anhydrous sodium sulfate is used as a drying agent to remove microscopic amounts of dissolved water in a solvent. It works by chemically reacting with the water by forming its hydrate, which is insoluble preferably in the solvent in this case dichloromethane. This allows one to filter off the crystals containing the water that would otherwise have remained dissolved in the dcm.

Why is anhydrous sodium sulfate used in organic chemistry labs?
Because of its affinity for water, anhydrous sodium sulfate is often used to dry hydrophobic solvents used in aqueous organic extractions. For example a water based sample is extracted for organic compounds using dichloromethane, or ethyl ether in a separatory funnel. The organic layer is passed through a buchner funnel holding anhydrous sodium sulfate, yielding dried solvent extract.
Why you use sodium extract for detection of elements?
we use sodium extract bcz it converts covalent compounds into ionic form..
Why can't you extract lead from lead oxide but you can with mercury and mercury oxide?
actually you can still extract lead from lead oxide, but you need to do this experiment with carbon or other reducing agent e.g. hydrogen and with a high temperature Celsius. But the reason that you can extract the mercury from the mercury oxides exactly is the higher reactivity of the lead. higher the reactivity means more difficult to extract the metals from the ore. so it is possible for lead to extract it from the lead oxide

Why use dichloromethane instead of ethanol to extract trimyristin?
because of the boiling point differences

Explain briefly how you would separate chloroform or dichloromethane extract from an aqueous solution using a separating funnel?
Both chloroform and dichloroform are denser than water. You will see two layer in separating funnel. The lower layer will be chloroform and upper layer would be aqueous layer.
How do you separate chloroform or dichloromethane extract from an aqueous solution using a separating funnel?
A separating funnel is used to extract mixtures of different densities. The separating funnel is cone shaped with a stopper at the top and a tap at the bottom. The liquids are added to the funnel, mixed and then allowed to settle so that the different densities settle out and are then slowly released separately through the tap once total separation has occurred.Separating chemicals from an aqueous solution requires knowledge of chemistry and molecules. Unfortunately, there is no such chemical as "chlorofon". There is a chemical known as "chloroform", however. Chloroform and Dichloromethane both form layers in water. These chemicals may be separated using distillation. When these two chemicals are present in water, the both separate and form layers. The separating filter can then be used to pull the chemicals from the solution.
