What happens when you heat copper sulphate over a Bunsen burner?
I think it becomes a black liquid which, when it cools becomes a black powder. it also bubbles and gives off a gas (oxygen I think) that means that the copper sulfate had the oxygen removed making it copper sulfide. (I'm not entirely sure but this is what happened in the practical. Cheers.
What chemicals form when malachite heated?
The formula for Malachite is Cu 2 CO 3(OH) 2.
Why does wood burn or combust?
When heated, wood gives off gasses. Those gasses combine with oxygen in the air, producing a chemical reaction that gives off heat. Rapid oxidation of a fuel is called combustion, or fire.
Copper plus water plus oxygen gives copper hydroxide is what type of reaction?
2Cu(s) + 2H2O(l) + O2(g) --> 2Cu(OH)2(s) is not a reaction which happens under any normal conditions. If it did we could say the copper is being oxidised.
What does Copper oxide with sulfuric acid gives what?
Copper sulfate and water :)
When cu and agno3 is heated what colour it gives and why?
It gives green color . Copper is more reactive than silver therefore it displaces silver from silver nitrate and forms silver + copper nitrate
Is it safe to breathe in the fumes from heated copper wire?
Hot copper wire gives off no fumes.However if you are talking about insulated copper wire, the insulation will give off fumes. Depending on the type of insulation it can be anywhere from totally safe to deadly!
How oxygen is prepared in lab using potassium chlorate?
Potassium Chlorate, when heated gives Potassium Chloride and Oxygen. You can use Manganese Dioxide as a catalyst to speed up the reaction.
Is it necessary to extract copper from earth?
yes because it can only be made by heating copper ore and carbon. The ore breaks down into copper oxide and the carbon then removes oxygen leaving the copper.. copper oxide + carbon = (arrow/ gives out) copper + carbon dioxide hpe it helped :)
