Briefly describe the applications of the nmr spectroscopy?
Expert
The major applications of NMR stereoscopy are the explanation of the carbon-hydrogen backbone of the organic compounds and the recognition of the relative stereochemistry of similar molecule.
Briefly describe the reason why it takes longer to heat a bucket of water than the cup of water?
Ohm's law (G. Ohm; 1827): The ratio of the potential difference among the ends of a conductor to the current flowing via it is constant; the constant of proportionality is termed as the resistance, and is distinct for different materials.
Kerr effect (J. Kerr; 1875): The capability of certain substances to refract light waves in a different way whose vibrations are in dissimilar directions whenever the substance is located in an electric field.
Write down any two elementary particles that have nearly infinite life time?
Describe why is heavy water employed as a moderator? Illustrate.
