What colourless gas is let off when you burn potassium permanganate?

there is no such thing. Potassium permanganate is a metallic purple crystalline substance that is solid at room temperature and can not be made a gas because it decomposes at 240 C. Long before it would become a gas. It dissolves in water rather well so you could make a water mixture and spray it but that would not be a gas. If you mix Potassium Permanganate with formaldehyde it creates a mild tear gas.

colourless gas.
What is observed when potassium bromide and sulphuric acid react?
H2 is formed which is a colourless gas but you can see bubbles. Br2 is also produced which is a dark orange/brown and turns the solution to this colour.
What describes oxygen?
Oxygen is a light, odourless and colourless gas

water (H20)
A colourless gas in trace amounts of air?

What happens when potassium permanganate is mixed with hydrochloric acid?
chlorine gas is produced
When the interaction between solid potassium permanganate and hydrogen peroxide happen what percentage posed by oxygen gas from the product mixture of water vapor and oxygen?
When sodium potassium permanganate and hydrogen peroxide interact 30% of oxygen gas is usually produced from the mixture.
What dangerous chemical is released when hydrochloric acid potassium permanganate?
Chlorine, a very toxic gas. (War gas in WW-I).
What gas does Potassium permanganate give off when it is cracked and turned black?
Oxygen gas in evolved. 2KMnO4 ---> K2MnO4 + MnO2(s) + O2
What color change occurs when chlorine gas is passed through a solution of potassium bromide?

Reaction of formaldehyde with potassium permanganate?
Benzaldehyde reacts with pottasium permanganate to generate benzoic acid (oxidation). Basic cnditions are required for the action of pottasium permanganate so sodium carbonate is used. But this gives sodium salt of benzoic acid which is soluble in water. To retrieve benzoic acid which is insoluble in water we use HCl.
Is NO a colourless gas?
Yes.
