Thermite is a high-temperature incendiary composition that can successfully reach temperatures of 2500 degrees Celsius. A thermite reaction--sometimes called a "Goldschmidt reaction"--refers to the very exothermic process occurring between a metal oxide such as Iron (III) oxide, Manganese (IV) oxide, or Copper (II) oxide, and a more reactive pure metal, such as Magnesium or Aluminium. The more reactive pure metal reduces the metal Oxide, Oxidizing itself and releasing a substantial amount of energy during the reaction. Usually the mixture is made by simply combining the ingredients, and then igniting it, which takes very high temperatures. The reaction releases so much energy, molten metal is produced as one of the products. This can often times become airborne when the reaction is sufficiently energetic, and poses major health hazards.
What else can I help you with?
Why would a large lump of copper oxide react slower with sulfuric than if copper oxide is used in powdered form?
A large lump of copper oxide has a smaller surface area exposed to the sulfuric acid compared to powdered copper oxide. This limits the contact between the copper oxide and the acid, leading to a slower reaction. Powdered copper oxide has a larger surface area, allowing for more efficient and faster reaction with the sulfuric acid.
What is the color of precipitate of copper II oxide from copper II hydroxide?
The color of the precipitate formed when copper(II) hydroxide decomposes to copper(II) oxide is black. When heated, the greenish-blue copper(II) hydroxide decomposes into black copper(II) oxide, which is the color of the precipitate.
What is the name of Cu2O?
CuO = Cupric Oxide Cupric = Cu2+ and is not Cu The correct answer would be CuO = Copper Monoxide Copper (II) oxide is the name of the compound CuO.
What color would be cupric nitrate if heated?
Cupric nitrate is initially blue when in its hydrated form. When heated, it will decompose to form copper oxide, turning black in color.
What is the scientific name for Copper oxide?
Copper Oxide is already the scientific name. If you meant using the symbols it would be CuO.
What is the copper oxide formula?
Copper oxide has two different forms. The first is a red power, Copper (I) oxide. Otherwise known as cuprous oxide or Cu2O. The second is a black powder, Copper (II) oxide. This is also known as cupric oxide or CuO.
When heated mercury oxide produces oxygen plus mercury what would be the combined mass of oxygen and mercury if 20g of mercury oxide were heated?
If 20g of mercury oxide were heated, the combined mass of oxygen and mercury would be 20 grams.
Copper and oxygen react to form copper II oxide?
When copper and oxygen react, they combine to form copper(II) oxide. This chemical reaction involves the transfer of electrons from copper to oxygen, resulting in the formation of the compound CuO. Copper(II) oxide is a black solid.
What is formula for copper III oxide?
If it existed the formula would be Cu2O3
What would happen if you diluted magnesium and copper with hydrochloric acid?
When magnesium is diluted with hydrochloric acid, it will react to form magnesium chloride and hydrogen gas. The reaction with copper and hydrochloric acid will not occur unless the copper is in a powdered form, as the acid cannot penetrate the protective oxide layer on the surface of solid copper. If powdered copper is used, it will react with hydrochloric acid to form copper chloride and hydrogen gas.
If you needed to use powdered copper sulfate in an experiment and were only supplied with clumps of copper sulfate which tool would you need convert the copper sulfate to usable form?
You would need a mortar and pestle to crush and grind the clumps of copper sulfate into a powdered form.
Why does copper carbonate decompose to make copper 2 oxide not copper 1 oxide?
Because it is easier. The molecular formula of copper carbonate is CuCO3. When it decomposes it loses a CO2 molecule. If it became Copper 1 oxide(Cu2O then it would have to combine with another molecule(releasing O). Instead it becames copper2 oxide(CuO) because that is an easier transition.
