Will copper displace the iron from iron oxide?
No, copper is less reactive than iron.
When you heat copper oxide and magnesium why do you get grey powder?
You get a grey powder because magnesium is higher up in the reactivity series than Copper - (magnesium is more reactive than copper) therefore when you heat it up there is a displacement reaction. That grey powder is actully magnesium oxide and copper e.g Copper oxide + magnesium = magnesium oxide and copper.
How do you separate copper from copper oxide?
I think you mean how do you extract copper from copper oxide, if so here's your answer. Take your copper oxide and heat it with something that is more reactive than copper. Carbon is a good example. The more reactive carbon will oxidise, taking the oxygen from the copper oxide leaving copper. copper oxide + carbon --> copper + carbon dioxide 2Cu0 + C --> 2Cu + CO2
What is copper thermite?
Copper thermite is a type of thermite where instead of the iron oxide, copper oxide is used instead. The reaction produces pure copper metal, but this thermite gets a little more splattery than the iron thermite.
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.
Cu forms two oxides For the same amount of Cu twice as much oxygen was used to form the 1st oxide than to form the 2nd one What is the ratio of the valencies of copper in the first and second oxides?
Copper (II) oxide - CuO; copper valence - 2 Copper (I) oxide - Cu2O; copper valence - 1 Ratio: 2
Will gold replace copper from copper sulfate solution?
No, gold is less reactive than copper.
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.
Is oxygen more reactive than copper?
if you mix copper and oxygen you get Copper oxide !
What metal reacts with copper oxide to make copper metal?
welllthere are number of metals which can serve the purpose.more scientifically speaking,the metals which have a greater tendency to be oxidised than copper willl do the work.for example zinc
What is copper oxides pH?
Copper(I) oxide and copper(II) oxide are both very insoluble in water. In practise i would expect no pH to be detected- however as they are basic oxides if any pH is detected it will be greater than 7.
Is copper more reactive then aluminium?
No, copper is less reactive than aluminum.
