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.

What gas do you get when you heat sulfuric acid?
It's just sulfuric acid vapor.
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
How does black copper oxide form?
CuCO3 + Heat --> CuO + O2 Green Copper Carbonate when heated will form Copper Oxide and Oxygen
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.
Copper II Hydroxide to Copper II Oxide?
CuO which is Copper(II) Oxide so... Cu(OH)2 + heat -----> CuO
What gas do you get when you heat sulfuric acid?
It's just sulfuric acid vapor.
What happens when you heat copper in oxygen?
copper oxide
What does heat and copper nitrate produce?
copper oxide, nitrogen and oxygen
What do you get if you heat copper sulphate?
i think copper oxide + sulphur dioxide

Is sulfuric acid soluble NaOH?
Sulfuric acid reacts violently with NaOH, producing sodium sulfate and water and lots of heat!
Would sulfuric acid decompose into a gas?
Depends on how you heat it
What happens when you heat copper?
Copper Oxide (CuO) + Water (H(sub2)O)
Copper II Hydroxide to Copper II Oxide?
CuO which is Copper(II) Oxide so... Cu(OH)2 + heat -----> CuO
Do heat release when ethanol react with sulfuric acid?
Yes, it is an exothermic reaction.
