Oxygen (O2)
CYCLOHEXANE - orange and blue flame with no soot....
Real money burns bright Orange...Counterfeit bills burn a Blue color
The blue flame is observable when complete combustion occurs, which is when the air valve is opened enough to allow the ideal amount of oxygen. The orange flame is due to the burning of carbon particles (soot) caused by incomplete combustion, which is an effect of too little oxygen available for the reaction.
I am not 100% sure what you are asking here however I will do my best to answer it. The gas that is used in most bunsen burners is methane (natural gas). This is not true for all labs as I have heard of labs using town gas (which is made from distillation of coal). A regular flame on a bunsen is orange this the coolest flame (300°C) and is rarely used. more common will be the blue flame which closer to 700°C. When leaving the bunsen for any length of time the orange flame should be left on as it is easy to observe and insures the safety of your fellow class mates.
To heat chemicals or substances in science lab for experiment. There is an air hole in the Bunsen burner where you can screw loose to have open air hole that is the blue flame which is hotter. When there is a close air hole then the flame would be orange in color which is not as hot compared to the blue flame.
Strontium is the element that turns a flame carmine red when it is burned. When strontium is present in a flame, it imparts its characteristic red color due to the emission of specific wavelengths of light.
Sulphuric acid turns to a bright orange.
the color of mercury is gray it has no color
Sodium (Na)
The bright orange color of the flame is due to the presence of sodium ions from the salt (NaCl) in the water. When heated, the sodium ions get enough energy to become excited and emit light in the form of an orange color. This phenomenon is known as flame coloration.
The product you are referring to is likely iodine. Iodine is a chemical element with a colorless solution that turns orange when it comes into contact with starch.
Potassium although sometimes it can look purple
Lithium turns red in flame tests.
Calcium typically produces an orange-red flame when subjected to a flame test.
The color that is produced is orange
Different elements added to a fire can change its color. For example, copper can produce a blue flame, while potassium can create a purple flame. The temperature required to produce these colors can vary depending on the specific element being used.
A calcium flame is typically a red-orange color, while a lithium flame is a bright red color. The difference in color is due to the specific wavelengths of light emitted by each element when they are heated in a flame.
