Raffinate is the residual material excluding the desired product which means that it is a product remains from solvent extraction without the main or desired substance. On the other hand, desired or main substance which is extracted by the solvent is called EXTRACT further to be processed in order to separate the solvent to be purified.
Liquid-Liquid extraction with ethyl acetate
It's used as a reducing agent. The carbon (or specifically the Carbon Monoxide produced by the heat of the furnace) "grabs" the oxygen from the ore (an oxide) producing Carbon Dioxide and the metal. The combustion of the carbon also provides the heat required for the extraction. If the ore is not an oxide, another method of extraction needs to be used.
Plants material contains Organic compounds along with salts and water, some organic compounds are polar and soluble in ethyl alcohol or ethyl acetate but some are non polar and soluble in ether or hexane, so two types of solvents may be used for plants extraction, the best way is to use non polar solvent first and extract the non polar compounds then use the polar solvent and extract the polar compounds.
The less reactive a metal is, the more likely it is to be found native in the Earth, or the easier it is to extract. By and large, the reactive metals, which are hard to extract, were discovered later.
That depends on what flower you want to extract essential oils from. I usually take a peak on wikipedia to see what compounds make up the essence, and then look up the chemical properties (namely the boiling point) of those compounds.

there is no difference
We can not extract DNA from RBCs as they are without nucleus. only the source of DNA extraction is Leukocytes, RBCs are not good source of extraction but we can extract DNA from immature RBCs.
Don't extract.
Extract puuls the air ,exhaust push the air
One tastes like almond and the other like vanilla
yes. Menstration will not effect an extraction.
DNA extraction from bacteria can be achieved in various ways. Yeast is the best resource to extract the DNA bacteria from using extreme rapid extraction method.
Hmm. I'm not positive, but I would assume that one is the extract of a grape seed and the other is the extract of a grapefruit seed.
