Why in some cases nujol technique is used In IR spectroscopy and in some other cases rest of techniques Is there any specific reason which technique to use and when?
you use nujol when you have a solid and combining the solid with the nujol forms a toothpaste consistency which you can then perform a neat IR on.
Which element has 77 protons in its nucleus?
Xenon. Take the atomic mass of 131 and subtract it's protons 54, to get 77 neutrons.
Why is natural gas more abundant than oil?
Natural gas lies in pockets throughout the strata of the earth's crust. Oil must be drilled, through many layers to access the vein, ir is not as agile as gas.
What is IR radiation in Ozone layer?
IR stands for Infrared radiation. Ozone has nothing to do with IR.
Can you use LEL meter used for checking hydrocarbon for checking hydrogen gas LEL?
NO, you cannot at present use a hydrocarbon gas detector which generally use IR absorption technology to detect hydrogen.
Which is the best preparation for IR spectroscopy solid liquid or gas?
liquid
Why organic liquid must be dried before IR spectrum is run?
many solvents are IR active. Organic liquids may have solvents in them if not dried properly and these solvents may interfere with the IR spectrum of the liquid compounds
How are IR rays produced in transmitter circuit of IR alarm?
when an electron drops from a higher energy state to a lower it emits a fixed frequency photon Gallium Arsenic Silicon Carbon have bright lines in a band of infrared can be varied colors depending on proportions this is monochromatic IR if you put parallel mirrors on either side of the the activated atoms you get a laser co2 gas laser ... Led Solid laser although IR is produced by burning sugar in a body and digital cameras can see that too

Which kind of rocket engines are used on the space shuttle?
liquid because ir never runs out <3
What is a active gas?
Absorption of energy from IR radiation can only occur when the wavelength of radiation and the wavelength of the bond vibration match. If a molecule has symmetry...for example no dipole, we say it is IR inactive. CO2 has no dipole....this would be an IR inactive gas...Cl2 as well. A gas that has a dipole would be IR active. Propene would be a nice example of an IR active gas.It possesses a dipole. One would see a signal around 1650.A:CO2 has no permanent dipole. However, when CO2 undergoes a bending vibration, its dipole moment changes from zero to some non-zero value. This vibration produces a change in dipole moment and is therefore IR active.

What was the name of the gas to kill the Jews in the concentration camps?
Zyklon B ir Carbon Monoxide
Where can I purchase a new IR cable?
There are different IR Cables but after some research, there are two solid online resources for a new IR cable purchase. You can order replacement IR control cables from www3.tivo.com/store/accessories.do. There are also IR cables of different types offered on Ebay.com, some of these offers are new and some are used. You can buy a new IR cable just about anyplace that sells electronic items. You can check at your local Walmart, Target and Rdaio Shack.

What does IR mean on my schedule It says I will be taking SPANISH IR. What does IR mean?
IR stands for: Introduction Remedial.
