What are 5 methods of analysis in chemistry?
Mass spectrometry, UV/Vis spectroscopy, NMR spectroscopy CNMR spectroscopy, Infra red spectroscopy
What type of electromagnetic radiation is absorbed by the sample in mass spectrometry?
Mass spectrometry doesn't use electromagnetic radiation, hence why it is not called Mass spectroscopy. Instead Mass spectrometry uses high energy electrons to ionize the sample molecules, which helps determine the mass of the molecules and any fragmented ions from the parent ion.
What is the mass of an ion with 107 electrons?
electrons have negligible mass. the mass of the ion depends on how many protons and neutrons are present.
The formula mass of a molecule or an ion is?
The formula mass of any molecule, formula unit, or ion is the sum of the average atomic masses of all atoms represented in its formula.
Is Raman spectroscopy is emmission spectroscopy?
no,it is reflection spectroscopy
What is metastable ion peak?
A metastable ion peak is a broad peak which appears at non-integral values of m/e in a mass spectrum. It is formed by a fragment ion. An unstable molecule such as an alcohol can undergo fragmentation during ionization ( collision with high energy electrons in ionization chamber of the mass spectrometer ) to give rise to a fragment ion. This fragment ion is also called the metastable ion.

Why mass spectroscopy only measure positive ion?
It's because negatively charged ions would not be attracted to the negative plate so it's not accelerated and thus it would not reach the detector.

What is the mass number of the ion?
The mass number of an ion remains the same as the element. This is because an ion gains or loses electrons which have minimal mass.
Advantages of Mass spectroscopy?
Mass spectroscopy is a highly sensitive technique that can accurately determine the molecular weight of a compound. It can provide information about the chemical structure and composition of a sample. Mass spectroscopy is also versatile and can be used in various fields like chemistry, biology, and environmental science.
What is the mass of an ion with 107 electrons?
electrons have negligible mass. the mass of the ion depends on how many protons and neutrons are present.
What are the differences among X ray Nuclear Mass Resonance Spectroscopy and Mass spectroscopy?
Everything. About the only thing they have in common is "you learn about them in analytical chemistry class."Except "Nuclear Mass Resonance Spectroscopy", which doesn't exist and I assume is an error that should have read "Nuclear Magnetic Resonance Spectroscopy".X-Ray spectroscopy gives you the conformation in a fairly direct (okay, it's actually not all that direct) manner.NMR spectroscopy mainly gives you chemical structure information; you can finesse it a bit (NOESY and related techniques) to give some conformational information.Mass spectroscopy is pretty much chemical structure only (and, again, it's not all that direct, it just tells you what fragments the molecule breaks apart into; figuring out how they fit together is your problem).
What has a -1 ion and has a small mass?
A hydroxide ion, "HO-".
How to test for chemicals in a molecular compound?
There are many of methods to test for "chemicals" in a molecular compound, you need to get more specific. i.e what "chemicals" we are looking for. For example if we have halide ions, to identify which halide ion is present add silver nitrate followed by ammonia solution. But theres always mass spectroscopy :p. There are may ways to test for "chemical". You need to be more specific. But theres spectroscopy. :p
