No.

∙ 9y agoThe emission spectrum of any element could be used to calibrate a spectroscope. Each element has a unique emission because it has a unique ground sate. When you are calibrating a spectroscope you are just setting a reference point.

Which property could be used to identify a compound in the laboratory?
Depending on the method many chemical or physical properties can be used. Examples: spectra of emission, color of ions in solution, formation of some precipitates, melting point, density, etc.
Why is sound not part of the electromagnetic spectrum?
Could it be that the frequency of sound waves are to low?
Could sixth graders identify different colas?
honestly what kind of question is this? what do you mean? could they identify different cola cans? flavor? what?
How can you identify if a new substance is made?
You would use trend of the periodic table to pinpoint the group or period of the substance. Then you would use group/period characteristics. If you can not find an element that matches, you will have to repeat the process which you created the element(if you created it). If you found the element then search around for more and team-up with a renowned chemist and prove it. ***It could take a few years to a coule decades to prove it***
How did Marie Curie challenge scientists ideas about the atoms?
There was an idea that an element could not be created or destroyed. Marie Curie showed that one element could become a new element. Destroying the old element to make a new one.
How can emission spectra used to identify presence of specific elements in a substance?
In atomic spectroscopy, each element has a unique spectrum. The atomic spectrum obtained from a sample is a combination of the spectra of each elemental component. We take the strongest line from the sample spectrum and determine which elements could have caused it (we call these "candidates"). We then look at the full spectrum from each candidate and see whether or not every major line is present in the sample spectrum. If so, we say that element is present.Then we subtract the spectrum (or spectra) of the element(s) we have determined to be present from the sample spectrum and repeat the same process with the next strongest line in the (leftover) sample spectrum. We continue repeating this process until all lines in the sample spectrum are accounted for.
When might it be helpful to identify an unknown element?
It is helpful to identify an unknown element when you are exposed to a lot of it. This element could be very dangerous to you.
Explain the effect of the nitrate ion in solution on the color emission?
The nitrate ion is the oxidizing agent in the compound without it you could not burn the chemicals and you could not produce a spectrum so there would be no emission of color
What is spontaneous emission of radiation from an element?
This could have many names such as 'decay', 'radioactive decay', or 'radiation.
The optical spectrum of the light from the sun could be used to identify what kind of atoms are present in or near the sun?
True
Who found helium?
Helium, the second most abundant element in the universe, was discovered on the sun before it was found on the earth. Pierre-Jules-César Janssen, a French astronomer, noticed a yellow line in the sun's spectrum while studying a total solar eclipse in 1868. Sir Norman Lockyer, an English astronomer, realized that this line, with a wavelength of 587.49 nanometers, could not be produced by any element known at the time. It was hypothesized that a new element on the sun was responsible for this mysterious yellow emission. This unknown element was named helium by Lockyer.
Could you define each element in the key elements in the communication process?
identify and define the elements of the communication process
What is the plural of the word spectra?
Spectra is the plural of spectrum. You could discuss the spectrum generated by an element in a star, and comparing more than one element, you would be comparing spectra. (Latin -um words form plurals like this, so you cannot refer to them as spectrums. Another example is datum, singular, and data, plural.)
What part of the spectrum could i detect with your sense of sight?
The visible spectrum
Which property could be used to identify a compound in the laboratory?
Depending on the method many chemical or physical properties can be used. Examples: spectra of emission, color of ions in solution, formation of some precipitates, melting point, density, etc.
What causes emission light on 2000 Lincoln LS to remain on?
the emission lights could be comming on because your catalytic converter is not working right.
What is a non spectrum disorder?
A "non-spectrum disorder" means a disorder that is not part of the spectrum being discussed. For example, it could refer to the disorders that are not part of the autism spectrum or disorders that are not part of the schizophrenia spectrum. (I have seen the term used in both these situations, so it depends on the context.) Non-spectrum disorders could refer to attention disorders, anxiety disorders, obsessive-compulsive disorder, and other developmental disorders.
