A good extraction solvent should have a strong solubilizing capability for the compound of interest, it should be immiscible or only weakly misciblewith the matrix solvent ( the first solution or mixture containing the compound from its natural source, e.g., water/ether. water/ chloroform, etc. If possible the extraction solvent should be non-flammable, non-toxic or of low toxicity, reasonably volatile, and of low eco-impact. Inexpensive and available, of high purity , and shelf stable. If one is determining the compound of interest by UV/Vis spectrophotometry or fluorescence, the solvent should have extremely low absobance or emission at the wavelength of analysis
• high solubility for the solute and low solubility for the carrier liquid.
• density difference vs. the carrier liquid greater than 150 kg/m. ...
• mid-level interfacial tension (5–30 dyne/cm)
• high resistance to thermal degradation.
Answer:
Its Particles move independently of one another and are widely spaced .
I hope its right, if not so please sorry :)
Answer: i know it not the answer
Explanation:
What is one time pad?
The one-time pad (OTP) is a theoretically unbreakable cipher. However, in practice it is of limited usability because it requires a pre-shared key of at least the same length as the message. This tool helps you encode or decode one-time pads if you have the key.
About Math Pad. MathPad is a tool for students to work on addition, subtraction, multiplication or division problems on a computer. MathPad is a word processor for math, not a tutorial or calculator. The student provides answers to math problems and the final answers can be checked in the Problem List mode for accuracy.
i hope you find the answer to your question
Answer:
Please see below
Explanation:
These two types of research, that is, in the laboratory and in the field, are very different from each other for a number of reasons. For one, the study is conducted on a much larger scale when it is done in the field as compared to when it is confined in the lab.
Tools such as PCR (polymerase chain reaction) would be common between the two since there is no substitute for it. However, other tools used that have various other purposes will be different between the lab and the field. For instance, a quadrant will be used to count plants in a field, but none is needed in the lab due to a smaller number of plants being studied.
Answer:
the variety of species in a community.
Explanation:
A species is a group of similar organisms that can mate and produce fertile offspring. a population is a group of organisms of the same species in an area. whereas a community is the populations of all of the different species or variety of organisms in an area.
