Is a flame test a good way to identify an element?
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.
How can you make a flame hotter on a Bunsen burner?
Turn the collar and the flame will get hotter
What does the flame in a gas cooker go out when you turn the gas 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.

How do you obtain a flame from a Bunsen burner?
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
What colour does just chlorine turn in the flame test?
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.

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.
Why do your fingers turn green when you wear real jewelry?
