High ionisation energy:
The high ionisation energy of helium (24.6 eV) makes it a potential gas to be used in plasma source.
The nitrogen gas is generally not used as a plasma gas in plasma based atomic emission spectrometry because the excited nitrogen emits a complex band spectrum that can cause undesirable spectral interference.
Polychromator is a type of simultaneous spectrometer. It has a fixed diffraction grating monochromator and multiple 'exit slits' with associated photomultipliers. Every of the photomultiplier is optimized to detect a specified wavelength corresponding to an element of interest. The emission radiation from the source is dispersed by the grating and sent through different exit slits to be detected by appropriate photomultiplier tube.
Why the current flow is always oppositte in direction to the conventional current direction? Ans) Availability of free electrons and application of potential difference are the c
Consider the reaction A → P. The change in concentration of A with time is shown in the given plot: (i) Predict the order of the reaction. (ii) Derive the mathematical expr
x grams of calcium carbonate was completely burnt in air.the weight of solid residue formed is 28 g.what is the vlue of x in grams?
Q. Can we apply Kinetic Molecular Theory to Solutions? Ans. The Kinetic Molecular Theory can also be applied to solutions. A solution is a distribution of one or more sub
Thermodynamic properties: Salts dissolve producing both cations and anions. It means that it is impossible to measure thermodynamic data for individual ion type. The solvation
Explain about the Dielectric Breakdown Dielectric Breakdown of a dielectric material is because of the excitation of electrons into the conduction band across energy
A moving particle may have wave motion, if: (1) Its mass is very high (2) Its velocity is negligible (3) Its mass is negligible (4) Its mass is very high and velocity
WHAT IS THE CHEMICAL EQUATION FOR LITHIUM SOLUTION WHEN AMMONIUM FLUORIDE AND AMMONIA ARE ADDED
From the point of view of "green chemistry" - why should reactions be carried out in CO 2 instead of using carbon monoxide or phosgene (2 reasons)? Apart from the compression of c
