How do you get powdered charcoal from a mixture of copper oxide and powdered charcoal?
To obtain powdered charcoal from a mixture of copper oxide and powdered charcoal, you can use a reduction reaction. Heat the mixture in a furnace or with a suitable heat source, as copper oxide will react with the charcoal (carbon) to form copper and carbon dioxide. The copper will be produced as a metal, leaving behind the powdered charcoal. After cooling, you can separate the unreacted charcoal from the copper.
Is gun powder a pure substance?
Gunpowder is not a pure substance. It is a mixture composed of potassium nitrate, charcoal, and sulfur in specific proportions. Each of these individual components maintains its chemical identity in the mixture.
How could you separate the components of a charcoal and sugar?
To separate charcoal and sugar, one method could involve adding water to the mixture and stirring, which would dissolve the sugar but leave the charcoal behind. Next, the mixture could be filtered to separate the dissolved sugar solution from the charcoal residue. Finally, the water could be evaporated to retrieve the sugar.
Why is gun powder a mixture?
The original black gunpower was a mixture of 2 elements (sulfur, charcoal) and a compound (saltpetre). Modern gunpowder s a mixture of several different copunds, including nitrocellulose and nitroglycerin.
What mixture could you separate using a sifter?
A sifter can be used to separate a mixture of powdered substances based on particle size. Larger particles will be retained in the sifter while smaller particles will pass through, allowing for effective separation.

How do you separate powdered charcoal from a mixture of copper oxide?
To separate powdered charcoal from a mixture containing copper oxide, just add water. Charcoal is considered quite a bit less dense than water and one set of tables gives the density as circa 400 kg.m-3 . Copper oxide is much more dense than water or charcoal. So the copper oxide will sink to the bottom and the charcoal will float to the top of the water. This can now be decanted and filtered leaving the charcoal on the filter paper which can be dried and to leave charcoal. Then with a separate filtration, the copper oxide and traces of water can be filtered and then dried.
What substance was traditionally made with a mixture of sulfur charcoal and potassium nitrate?
Gunpowder was traditionally made with a mixture of sulfur, charcoal, and potassium nitrate.
Mixing powdered charcoal and oxygen at room temperature?
Mixing powdered charcoal and oxygen at room temperature can create a highly flammable mixture. If ignited, this mixture can result in a rapid combustion reaction due to the high reactivity of charcoal with oxygen, leading to a release of heat and light energy. It is important to handle this mixture with caution to avoid any potential fire hazards.
What is made from sulfur charcoal and potassium nitrate?
This is the composition of gunpowder.
How do you separate mixture of sulfur and charcoal?
You can separate a mixture of sulfur and charcoal by using a method called sublimation. Heat the mixture in a test tube or flask, where the sulfur will sublimate (turn into gas) and leave the charcoal behind. The sulfur gas can then be collected and condensed back into solid form.
How do you Separate the mixture of charcoal and crystals of iodine?
By heating it at low temperatures.
Is gun powder a pure substance?
Gunpowder is not a pure substance. It is a mixture composed of potassium nitrate, charcoal, and sulfur in specific proportions. Each of these individual components maintains its chemical identity in the mixture.
How do you separate the mixture of sulfur from charcoal?
One way to separate sulfur from charcoal is through sublimation. Heat the mixture in a container where sulfur can vaporize and then condense on a cooler surface, separate from the charcoal. This method takes advantage of the difference in sublimation temperatures between sulfur and charcoal.
How could you separate the components of a charcoal and sugar?
To separate charcoal and sugar, one method could involve adding water to the mixture and stirring, which would dissolve the sugar but leave the charcoal behind. Next, the mixture could be filtered to separate the dissolved sugar solution from the charcoal residue. Finally, the water could be evaporated to retrieve the sugar.
You are given a mixture of sulfur potassium nitrate and carbon and asked to separate the components so you end up with a pile of solid sulfur a pile of solid potassium nitrate a pile of solid carbon?
So, you have a pile of gunpowder and you want to separate it. Right? Here's are some clues: Saltpeter (potassium nitrate) is soluble in water. Sulfur and carbon are not. Furthermore, sulfur is soluble in acetone but carbon is not. This assumes that you have pure carbon and not charcoal powder. Depending on the quality of the charcoal powder, it could be more or less soluble in different substances. But let's just take your teacher at his word: Carbon is carbon. If there is enough differential in particle size you could sift the mixture through a screen but that doesn't guarantee you'll get ALL the carbon, sulfur or saltpeter out of the mix. If the particles are all the same size that won't work at all. (OR) here is a better phrased answer: Answer: Gunpowder is a mixture of sulphur, charcoal and potassium nitrate (nitre). When water is added to the mixture potassium nitrate dissolves. The mixture is then filtered. The filtrate is potassium nitrate solution while the residue is a mixture of sulphur and charcoal. The filtrate is evaporated on a sand bath to obtain nitre back. When carbon disulphide is added to the residue, sulphur dissolves. When this mixture is filtered the filtrate is sulphur solution while the residue is charcoal. Leaving it open evaporates the sulphur solution. Carbon disulphide evaporates and sulphur crystals are left behind.
How do you make gun powder?
A mixture of potassium nitrate, charcoal, and sulphur in a 75:15:10 ratio
