What flame colour does copper chloride give?
Flame colours depend on just the metal ion. All copper compounds give the same colour, green.
Why shouldn't magnesium be burned in pure oxygen?
magnesium should not be burned in pure oxygen because the flame will be white or luminous.
What color does copper give off?
Copper gives off a green flame when burned. So, green.
What is the evidence that indicates that both physical and chemical changes occur when a copper wire is heated in a Bunsen burner flame?
When a copper wire is heated in a Bunsen burner flame, the copper's color changes to become a glowing red. It won't be restored to its original appearance after cooling. Instead, it becomes a black material called copper (II) oxide, which is 79.9% copper and 20.1% oxygen (was 100% copper before it was burned). This chemical change occurred as the oxygen in the air combined with the copper during the heating process.
What colour flame would indicate ethane burning in excess oxygen?
orange
What is the colour flame of strontium chloride when it burned?
red

What color does copper nitrate burn in a flame test?
The colour of any sample containing copper ions burns with a bluish green flame in the flame test.
Why shouldn't magnesium be burned in pure oxygen?

What colour flame do you get when you burn copper chloride?
A bright green color is imparted to the flame by copper chloride

What colour is the flame of copper sulphate when heated?
it is like the color but gold more
What colour flame does sulfur burn with?
Iron is a sort of sparkly-black when it is burned.
Does burning copper in a naked flame increase its weight?
Copper doesn't burn in a naked flame, but will simply turn black. This is due to its reaction with the oxygen in the air forming black copper (II) oxide CuO. Therefore, as the copper has now reacted with oxygen it will weigh more than it did.
What colour flame would indicate ethane burning in excess oxygen?
orange
What alkynes produces the hottest flame when burned in oxygen and is primarily used as a fuel gas?
Acetylene
