Why the colour of heated copper powder becomes black when air is passed over it?
the copper reacts with 02 in the air to make copper oxide, which is black 2Cu+O2--> 2Cuo
How much hydrogen gas is produced when steam is passed over hot iron?
One percent of the total mass of the iron will be released as hydrogen gas.
What would happen if copper metal was added to water?
when copper is put with water it turns green like the statue of liberty it is actually a browny bronze colour but when water and other chemicals react with it, it chages colour to a green colour
Why you use the steam trap to separate any liquid content?
Steam traps help out in a couple of ways: Where steam is being passed through a turbine, entrained liquid droplets could cause problems when the impact the blades of the turbine. Where steam is being used to heat something, the liquid has already lost the heat of vaporization, so it is not worth transporting for heating purposes.
What are the advantages of copper pipe fittings over plastic?
The advantages of copper pipe fittings over plastic is that copper does not bend or break as easily as plastic, so it lasts longer and is much more reliable as well.
What is observed when air is passed over heated copper powder?
The copper becomes black!
When steam is passed over red hot iron?
Hydrogen gas is produced.
What will happen if hydrogen gas is heated over copper oxide?
the copper oxide will turn red
When hydrogen gas passed over heated cupric oxide?
When hydrogen gas passed over heated cupric oxide, the hydrogen is oxidized and displaces copper from the copper oxide as metallic copper, because hydrogen is higher than copper in the electromotive series. Water vapor is also produced by the reaction.

What happens when hydrogen reacts with copper oxide?
When Hydrogen Is Passed Over Hot Tubgsten Oxide (WO3) WO3 + 3H2 ----------------> 3H2O + W
What happen to acadians?
The Acadians were passed over to the French and British many times then after Confederation they became part of Canada.
When hydrogen is passed over copper oxide copper and water are formed what is the balanced equation for this and which of the chemicals are elements compounds reactants products metals and non-metals?
Assuming it's copper(II) oxide, the equation for that reaction is: CuO + H2 --> H2O + Cu. Reactants: copper oxide and hydrogen gas. Products: Water and copper. Elements present: hydrogen, copper. Compounds present: copper oxide, water. Metals: copper. Non-metals: hydrogen.
What will happen if ammonia is passed over heated litharge?
lead oxide changes to lead ,water and nitrogen gas is formed
Write word and balanced symbol equation for the reaction of iron and steam?
my best guess is tht u posted this question then answered it w/ non-answerWhen steam is passed over iron it creates a magnetic oxide of iron called triiron tetroxide, Fe3O4.
How does iron react with steam when heated?
Fe is the chemical symbol for iron. When iron reacts with steam it corrodes, or rusts.
