Gold doesn't actually burn, but if subjected to high enough heat it can produce a bright bluish-white light due to incandescence.
Limitations:The nichrome wire may still have impurities after cleaning in the hydrochloric acid. This may have an affect on the colour of the flame. This in turn will have an affect on the results obtained, having an affect on the whole experiment.Another limitation is that the flame already burns red/orange so this may make it a judgement call of what colour the flame is. If this judgement is incorrect the results of the experiment will be affected.The test cannot differentiate between all elements. Several metals produce the same flame colour. Some compounds do not change the colour of the flame at all.Sodium is present in most compounds and will colour the flame. Sometimes a blue glass is used to filter out the yellow of sodium.The test cannot detect low concentrations of most ions.
Turn the collar and the flame will get hotter
The flame goes out because you turned it off.

No. If you burn an element, you will turn it into a compound (most commonly [element burnt] oxide). Which will not be an element.
If you talk about gold fish colour then it is a common sense that it is naturally gold.
Unfortunately the visible colors produced in gold flame are too weak to be useful. About tenth of sodium yellow, calcium red, or potassium violet flames, which also are clearer to the expert eyes.
When sodium oxide is burned, it typically produces a yellow flame.
Broiling is the same as grilling, not too hot, turn frequntly until a nice brown colour, not burnt.
You turn the air admittance ring at the base of the Bunsen burner until it is fully open. this allows the hottest flame to be produced and has a blue colour
Chlorine gas itself does not emit a colored flame when subjected to a flame test. Instead, it will impart a green color to the flame when a sample containing chlorine (such as a chloride compound) is included in the flame test.

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.
if the colour is similar to gold then unfortuanatrly it could be brass
Being inert and unreactive, pure gold does not react with any acid except aqua regia. Thus its colour does not alter.
Copper (II) nitrate burns with a blue-green flame, characteristic of copper compounds.
the cigarette turn to full burnt
