Why did the penny turn gold when heated in the burner in the burner flame?
When a penny is heated in a flame, the copper metal reacts with oxygen in the air to form copper oxide. Copper oxide has a black color, but when it is heated at high temperatures, it can react with carbon in the flame to form a thin layer of elemental gold on the penny's surface, giving it a gold color.
How does a yellow flame on a Bunsen burner make things black but the roaring flame doesn't?
The flame of a Bunsen burner that is yellow in color will leave a black carbon residue due to the incorrect mixture of oxygen into the flame. Because there is not enough oxygen for complete combustion, the carbon reside is left behind. When the Bunsen flame has a sufficient amount of oxygen mixed in, hence the 'roaring flame', it has a blue color and does not leave a carbon residue due to complete combustion of the acetylene gas.
What is turned to used to change the type of flame a Bunsen burner produces?
You would turn the collar on a Bunsen Burner so that the holes are exposing the flame to more oxygen to produce a blue flame. Close the holes by turning the collar to turn it back to the yellow (dirty) flame.
Why does the Sulfur Crystal burst into blue flames when it is in a fire?
The colour is due to electronic transitions within each atom. Electrons move up into high energy levels when heated in the fire. The electrons then move back down into their original state upon cooling in the air around the fire. When the electrons move down energy levels, specific amounts of energy are released, with the colour of the flame dependent on the wavelength of the light, which in turn depends on the distance (number of energy levels) that the electrons have to fall. Try searching on youtube for flame tests (I find "Mrericsully"'s videos to be quite good) for more similar reactions, particularly involving alkali earth metals
What color does Iron chloride turn in flame test?
Iron chloride does not produce a distinctive color in a flame test. It typically appears as a pale yellow-green flame due to the presence of the chloride ion rather than the iron ion.
How does a flame's color turn in color blue?
A flame turns blue when it achieves complete combustion, meaning there is enough oxygen present for the fuel to burn efficiently. The blue color is due to the presence of carbon dioxide and water molecules in the flame, which emit a blue light as they undergo chemical reactions.
What color will a flame turn if a ghost is near?
Blue
What color is the flame of Strontium nitrate?
The flame of strontium nitrate is red. It produces a bright red color when ignited.

What color does Iron (III) chloride turn in flame test?
Iron (III) chloride does not produce a distinct color flame during a flame test. This compound is typically used more for other chemical tests rather than flame tests for cation identification.
What happen to the color of the flame when powdered charcoal was sprayed on it?
When powdered charcoal is sprayed onto a flame, the color of the flame may turn a bright orange or yellow due to the carbon particles burning and emitting light. The charcoal acts as a fuel source, enhancing the combustion process and intensifying the color of the flame.
Color of flame in a complete combustion of gas from Bunsen burner?
When the air hole is covered on the Bunsen Burner its oxygen supply is made smaller. This makes the flame turn YELLOW - This is considered to be the safety flame as it is the most visible to the eye and it radiates less heat. When the Bunsen burners air hole is fully open there is a super heated blue flame which is the product of complete combustion. Hope this helped :)
When tissues and organs are deprived of oxygen what color will they turn?
BLUE
