Heating blue coloured powder of copper li nitrate in a boiling tube?
Heating blue colored copper nitrate in a boiling tube will cause it to undergo thermal decomposition, producing brown nitrogen dioxide gas, oxygen gas, and copper(II) oxide residue. The color change is due to the formation of copper(II) oxide. This reaction is a common demonstration of the decomposition of metal nitrates when heated.
What happen when chloroform is heated with solver powder?
When chloroform is heated with silver powder, a reaction occurs that leads to the formation of elemental silver and hydrogen chloride gas. This reaction is known as the dehydrochlorination of chloroform. Silver powder acts as a catalyst in this reaction, facilitating the decomposition of chloroform into its constituent elements.
How do you make silver nitrate from powder?
To make silver nitrate from powder, you would need to dissolve silver oxide or silver metal in nitric acid. The reaction produces silver nitrate and water. Make sure to use appropriate safety precautions when working with nitric acid, as it is corrosive and can be hazardous.
What is the colour of lead nitrate powder?
white powder and colourless crystals.
What is the best oxidizer for black powder?
Potassium nitrate is the oxidizer used in black powder. Although other oxidizers are stronger(potassium perchlorate for example), it must not be replaced by them. If the term used is black powder, potassium nitrate is the only oxidizer that ought to be used.

What is the colour of lead nitrate powder?
white powder and colourless crystals.
What is gunpowder made out of?
Gunpowder is typically made of a combination of charcoal, sulfur, and potassium nitrate (also known as saltpeter). These three components are mixed together to create a chemical reaction that produces the explosive force when ignited.
What is the best oxidizer for black powder?
Potassium nitrate is the oxidizer used in black powder. Although other oxidizers are stronger(potassium perchlorate for example), it must not be replaced by them. If the term used is black powder, potassium nitrate is the only oxidizer that ought to be used.
What are the uses of potassium nitrate?
Potassium nitrate is used to make fireworks and black powder (which is used in gun powder).
What happens when boiling water is mixed with white powder?
When boiling water is mixed with white powder, it can result in a chemical reaction that may cause the mixture to change color, release gas, or produce heat. The specific outcome depends on the properties of the white powder and the temperature of the water.
What happen when ethanol is heated with bleaching powder and water?
When ethanol is heated with bleaching powder (calcium hypochlorite) and water, it can undergo oxidation to form acetaldehyde. The bleaching powder provides the chlorine necessary for this oxidation reaction to occur. This reaction is typically used in organic chemistry for the transformation of alcohols into aldehydes or ketones.
What is the balanced chemical equation for the chemical reaction between manganese dioxide and aluminum powder .what happens if manganese powder is heated with aluminum oxide?
When manganese dioxide is heated with aluminium powder, the following reaction takes place: These displacement reactions are highly exothermic. The amount of heat evolved is so large that the metals are produced in the molten state. On the other hand when manganese is heated with aluminum oxide no reaction takes place as aluminum is more reactive than manganese and is placed higher in the activity series.
What is formed when zinc is heated with sulfur?
When zinc is heated with sulfur, zinc sulfide is formed. This reaction produces a white/yellowish powder of zinc sulfide.
What is observed when air is passed over heated copper powder?
When air is passed over heated copper powder, the copper powder will react with the oxygen in the air, leading to the formation of copper oxide. This reaction can result in a color change in the copper powder from its original metallic color to a reddish-brown color.
