What is the colour of the flame seen when sulphur burns in air?
blue
What is the gas in the gas taps and comes from under the north sea. It burns with a blue flame if there is plenty of air?
methane is in gas taps comes fro under the north sea and burns with a blue flame if there is plenty of air from gemma
State two observations that can be made from burning magnesium?
It can be observed that magnesium burns in air with a dazzling white flame. A white powder known as magnesium oxide is produced. Magnesium burns in oxygen present in the air to produce magnesium oxide.
When evaporating dish is held over the flame ( air holes are closed )?
I assume the air holes are on a bunsen burner? In which case, when the air hole is closed the flame glows yellow, is less hot, and is more like the flame on a wax candle. When the air hole is opened, air is drawn in and the flame burns blue and produces a fiercer heat.
What is the color of Potassium oxide?
When freshly cut it is silvery in colour but it quickly tarnished as it reacts with oxygen in the air. all alkali metals give characteristic flame colour wich are used to identify them potassium has the colour LILAC
What is the colour of the flame seen when sulphur burns in air?
blue
Can sulfur burn?
Sulphur burns in air (oxygen ) to give sulphur dioxide. S + O2 ---> SO2
What metal burns with a silver flame in air?
magnesium
When sulfur burns in air does it make sulfur oxide or sulfur dioxide?
It makes Sulphur Dioxide. and little Sulphur Trioxide.
Why flame on a candle burns erect?
The flame heats the air and it is lighter so it goes upwards.
Substance produced when sulfur burns in air?
The product of this reaction is the sulphur dioxide - SO2.
What is the gas in the gas taps and comes from under the north sea. It burns with a blue flame if there is plenty of air?
methane is in gas taps comes fro under the north sea and burns with a blue flame if there is plenty of air from gemma
Why the central blue cone in the blue flame is unburnt gas?
because no air enters it. The air burns gas.
How white flame is formed?
Yes, it is possible to have a white flame. A good example of a white flame is the flame with which a magnesium wire burns. When magnesium wire is burnt in air(oxygen), it burns with a bright white flame.

A Bunsen burner burns with the hottest flame when its hole is fully open because this allows plenty of gas from the air to reach the flame What is this gas?
Oxygen
