Because it is easier. The molecular formula of copper carbonate is CuCO3. When it decomposes it loses a CO2 molecule. If it became Copper 1 oxide(Cu2O then it would have to combine with another molecule(releasing O). Instead it becames copper2 oxide(CuO) because that is an easier transition.

How do you make copper oxide from copper carbonate?
Carbonate Decomposition Aim: To investigate the decomposition of a carbonate. Equipment: · Copper Carbonate (CuCO3) · Limewater · Bunsen Burner · Matches · Test tubes · Clamp and stand · Hydrochloric Acid · Electronic Scales Method: 1. Weighed Copper Carbonate by taring empty test tube. 2. Placed some Copper Carbonate in a test tube fitted with gas delivery tube and stopper. 3. Clamped the test tube to the stand at a slight angle. 4. Half filled another test tube with limewater and placed the other end of gas delivery tube into it. 5. Using a small blue flame gently heated the carbonate. Observed what happened. 6. Removed gas tube from limewater before turning off the Bunsen burner. 7. Allowed to cool 8. Weighed the remaining Copper Carbonate. 9. Added approximately 5ml of Hydrochloric Acid to the solid residue (Copper Oxide) from the decomposition reaction. 10. Transferred a small amount of original Copper Carbonate to new test tube and added same amount of Hydrochloric Acid to that. Recorded observations. Results: Observations from Decomposition: The limewater turned milky. Observations from HCl & Copper Oxide: Small bubbles. Hardly a reaction. Observations from HCl & Copper Carbonate: Bubbles & fizzing. Small amount of heat generated. Turned milky green in colour. Reacted immeadiately. Conclusion: The limewater proved that Carbon Dioxide was produced as a result of thedecomposition reaction. The Copper Oxide test showed that theoretically there should be no reaction with HCl. Copper Carbonate, however, theoretically, should react. Evaluation: Overall, the experiment was a success except for the fact that the HCl shouldn'thave reacted with the Copper Oxide but did. This is probably due to the fact there was some Copper Carbonate still stuck to the side of the test tube and the HCl reacted with that.
What acid is used to make copper sulphate?
Sulfuric acid is commonly used to make copper sulfate by reacting it with copper oxide or copper carbonate. The reaction forms copper sulfate and water, with sulfuric acid providing the necessary protons for the reaction.
What does magnesium and copper oxide make?
Magnesium + copper oxide --> magnesium oxide + copper
Which compounds make up copper carbonate?
Copper(II) Carbonate (or Cupric Carbonate) is made up of Copper ions, and Carbonate ions. The coppers have a +2 charge, and carbonate has a -2 charge. The formula is Cu(II)CO3
What does sulfuric acid plus copper carbonate make?
Sulfuric acid and copper carbonate react to produce copper sulfate, carbon dioxide gas, and water.
How to prepare dry black copper II oxide from copper carbonate hydroxide?
You place the copper carbonate hydroxide sample in a stainless steel tray and then the tray in an electrically heated furnace, able to reach temperatures above 500 degrees centigrade (measuring thermocable). Then the furnace door is closed and the furnace is switched on. When a temperature of 500 oC in the furnace has been reached, the calcination needs to be carried out over a duration of four hours. The product is pure copper oxide (more accurately: cupric oxide)
Does calcium carbonate decompose to make calcium oxide and water?
Calcium oxide, or quicklime, can be decomposed chemically into its components, calcium and oxygen. Calcium is an element and cannot be decomposed chemically.

When copper ii hydroxide and sodium nitrate is heated?
When copper II hydroxide and sodium nitrate are heated together, they may undergo a decomposition reaction. Copper II hydroxide will decompose into copper II oxide and water, while sodium nitrate will decompose into sodium nitrite and oxygen.
What acid is used to make copper sulphate?
Sulfuric acid is commonly used to make copper sulfate by reacting it with copper oxide or copper carbonate. The reaction forms copper sulfate and water, with sulfuric acid providing the necessary protons for the reaction.
What does magnesium and copper oxide make?
Magnesium + copper oxide --> magnesium oxide + copper
What is mixed with copper oxide to make copper sulphate?
Sulphuric acid is mixed with copper oxide to make copper sulphate through a chemical reaction.
Which compounds make up copper carbonate?
Copper(II) Carbonate (or Cupric Carbonate) is made up of Copper ions, and Carbonate ions. The coppers have a +2 charge, and carbonate has a -2 charge. The formula is Cu(II)CO3
Why does copper carbonate make greenium a compound?
Copper carbonate reacts with acid to form copper II ions which are blue-green in color. When these copper ions are mixed with hydroxide ions they form copper hydroxide which is then oxidized to form green copper oxide. This green pigment mixed with other materials becomes "greenium."
What insoluble base used to make copper sulphate?
Sodium hydroxide is commonly used to make copper sulfate from copper oxide, which is insoluble in water. The reaction between copper oxide and sodium hydroxide forms copper sulfate and water.
What does sulfuric acid plus copper carbonate make?
Sulfuric acid and copper carbonate react to produce copper sulfate, carbon dioxide gas, and water.
What else do you need apart from oxygen to make CuCO3?
Copper and carbon along with oxygen make up copper(II) carbonate. However you cannot make it simply by mixing them together. A possible pathway might be to get to sodium carbonate perhaps CO2 + NaOH might be the way and then make some copper sulfate by reacting it with H2SO4, mix your sodium carbonate solution with copper sulfate solution and copper carbonate should precipitate out.
