green
Copper gives off a green flame when burned. So, green.
Flame colours depend on just the metal ion. All copper compounds give the same colour, green.
None. Using flame spectral analysis, we can use a prism or other device to determine the color of various metals. Nitrate gives no color. The purpose of the test is to give metal detection, qualitatively. Testing for nitrate is another test, not involving flame.
Sodium hydroxide does not produce a distinct color in a flame test. It is the sodium ions that give a bright, persistent yellow color to the flame.
Sodium colours the fire bright yellow; Lithium - red; Calcium - dark red; Copper - green, blue-green; Potassium - blue; Magnesium - white
Selenium nitrate typically gives a pink or reddish flame color when subjected to a flame test.
All sodium salts will give a yellow flame test, because of the metal sodium in the compounds.
The yellow color of the flame is due only to sodium.
Copper gives off a green flame when burned. So, green.
Barium salts, such as barium chloride or barium nitrate, are commonly used to produce a green flame when burned. The green color is a result of the specific wavelength of light emitted by the barium ions during the combustion process.
Flame colours depend on just the metal ion. All copper compounds give the same colour, green.

A: If you put a piece of copper wire on any type of flame (most preferably cooking flames), then you would observe that they produce a green color in the flame. Sometimes, it might give youa blue tinge but if it doesn't, it doesn't mean that there's something wrong with the copper you're using.
The blue color in the solution is due to the formation of copper(II) nitrate, as the copper turnings react with the silver nitrate solution. This reaction forms copper(II) ions which give the solution a blue color, indicating the presence of these ions in the solution.
You need to give more information. What color was the coin after the reaction, and did the silver nitrate solution change color?
It is a white solid that is soluble in water According to http://www.ilumina-dlib.org/browseRecord.asp?fileName=651-marc.xml&fileLocation=LiveData&sortBy=guid&orderBy=asc&taxon1=Chemistry&taxon2=&taxon3= it produces an orange flame
