What would be observed if the flame tests were viewed through a spectroscope?

Emission spectrum of the elements placed in the flame. The flame test is usually applied when Sodium, Potassium or other such metals are thought to be present since they give a very noticeable result - Sodium gives orange colour to the flame (as it does to sodium street lighting!) - Potassium gives a lilac colour etc

∙ 14y agoWhen you add the different salts to the flame, a new color will produce, and upon looking at it through a spectroscope, you'll see new strands of colour for each and every flame. And since each Salt is different, you'll also have a different spectrum.

Why a gauze is often placed over a burning flame for heating an object?
To prevent flame impingement on the vessel being heated, which could damage the vessel. A flame cannot pass through a gauze (or screen). as a proof you could set up a bunsen burner beneath a wire gauze. Turn the gas on and ignite the gas above the gauze. you will notice the flame will stay above the gauze. If you ignite the flame beneath the gauze and lower the gauze into the flame, the flame will not pass above the gauze. Yet, if you light both below and above the gauze you will have flame on both sides. Indicating that flames impinging on the gauze do not burn the gas completely and the gas will pass through the gauze.
How do you find burning velocity?
Laminar flame speed is a property of a combustible mixture.[1] It is the speed at which an un-stretched laminar flame will propagate through a quiescent mixture of unburned reactants. Laminar flame speed is given the symbol sL. According to the thermal flame theory of Mallard and Le Chatelier, the un-stretched laminar flame speed is dependent on only three properties of a chemical mixture: the thermal diffusivity of the mixture, the reaction rate of the mixture and the temperature through the flame zone:is thermal diffusivity,is reaction rate,and the temperature subscript u is for unburned, bis for burned and i is for ignition temperature.While the laminar flame speed is a property of the mixture alone, the same is not true for turbulent flame speed - or turbulent burning velocity as it is more correctly called. As flow velocity increases and turbulence is introduced, a flame will begin to wrinkle, then corrugate and eventually the flame front will be broken and transport properties will be enhanced by turbulent eddies in the flame zone. As a result, the flame front of a turbulent flame will propagate at a velocity that is not only a function of the mixture's chemical properties but also properties of the flow and turbulence.
What color flame burns the hottest?
Its not a Blue Flame (blue flame)its a white flame. i believe it can get around 1,000degrees
Which flame on a Bunsen burner is silent?
The silent flame on the Bunsen burner is the yellow/orange flame.
Is the blue or yellow flame noisier on a Bunsen burner?
The Blue Flame Will Be Noisier. The Yellow Flame Is Called A Safety Flame Because Everyone can See it. There Are Two Blue Flames: Medium Roaring The Roaring Flame Has A Blue Cone In The Middle Of The Flame And It Is The Hottest. It Also Has More Oxygen. But Overall, The Blue Flames Will Be Noisier Than The Yellow Flame.
Describe the common characteristics of flame tests that would be observed if a spectroscope were used?
Not a god danm thing it's utterly pointless don't even bother chemistry isn't even important.
Glowing gases observed during combustion?
Glowing gases observed during combustion is called a "flame."
When zinc solution is burned what flame color is observed?
orange
What precautions must be observed if the flame blows itself out?
So what is really the answer?
What happens a flame test?
Electrons are excited to higher energy levels and their emissions are observed.
What precautions must be observed when the flame blows itself out?
what the! why can't you give answers answers.com
Why flame is observed during the burning of a substance?
During combustion, energy is released. Some of this energy takes the form of light, making the flame visible.
Why is a yellow flame observed when glass rod heated?
Sodium of course...
Strike back occurs when the flame is observed at the gas spud and the flame turns green. What must one do when strike back occurs?
back up
What are two ways to observe the emission spectra of a chemical?
The emission spectrum is the electromagnetic radiation spectrum of a particular chemical. The major ways this is observed is through special equipment designed for it, though flame emission spectroscopy is its own method, wherein burning a chemical produces a particular color of flame.
Flame color of magnesium sulfate?
it burns white, but when mixed with potasium nirtate, it burns purple/violet
Is there a way to test to see if it is potassium nitrate or ammonium nitrate?
Flame test. Dip a piece of platinum wire into concentrated nitric acid, and then roll it in the sample. Put the wire over a Bunsen flame. If a lilac flame is observed, it is potassium nitrate.
