Most metal oxides react with dilute acids.The reaction between an insoluble metal oxide and a dilute acid is often quite slow so it is possible to observe the progress of the reaction as the solid reactant disappears as a soluble product is formed. Hence to enhance the speed of the reaction, excess Copper Oxide is used in preparing Sulphate Salt.
Because some of the copper carbonate will evaporate in the form of carbon dioxide.
To make sure that the reaction thatoccurredhas finished.
because copper sulphate crystals can't be prepared without sulphuric acid
To test an experiment.
to get copper sulphate and water
It's just sulfuric acid vapor.
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
CuCO3 + Heat --> CuO + O2 Green Copper Carbonate when heated will form Copper Oxide and Oxygen
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.
CuO which is Copper(II) Oxide so... Cu(OH)2 + heat -----> CuO
It's just sulfuric acid vapor.
copper oxide
copper oxide, nitrogen and oxygen
i think copper oxide + sulphur dioxide

Sulfuric acid reacts violently with NaOH, producing sodium sulfate and water and lots of heat!
Depends on how you heat it
Copper Oxide (CuO) + Water (H(sub2)O)
CuO which is Copper(II) Oxide so... Cu(OH)2 + heat -----> CuO
Yes, it is an exothermic reaction.
