Chemical formulas:
- CuO, Cu(II)-oxide, cupric oxide (monocopper oxide), black
- Cu2O, Cu(I)-oxide, cuprous oxide (dicopper oxide), red
- sulfuric acid, H2SO4
CuO + H2SO4 --> CuSO4 + H2O , cupric sulfate, blue solution
Cu2O also reacts with dilute sulfuric acid forming CuSO4 by:
Cu2O + 2 H2SO4 --> CuSO4 + H2O + H2, cupric sulfate, blue solution
Copper carbonate + sulphuric acid = copper sulphate + water + carbon dioxide
Get copper suphate + carbon dioxide + water + residual of the original component not in the proper proportion.
Copper plus oxygen react to form copper oxide. This reaction can be represented by the chemical equation: 4Cu + O2 → 2Cu2O.
There are two different copper oxide formula's:2Cu + O2 -> 2CuO (black Copper(II) oxide)or4Cu + O2 -> 2Cu2O (red Copper(I) oxide)
It is the direct combination of two elements or oxidation of copper. 2Cu + O2 = 2CuO its a synthesis reaction!
SO4H2 + 2Cu --> SO2 + 2CuOH
As in most chemical reactions, an increase in temperature increases the rate of reaction between copper oxide and acid.
Balanced equation: CuO + 2HCl --> CuCl2 + H2O Word equation: One mole of copper (II) oxide plus two moles of hydrochloric acid produces (or yields) one mole of copper (II) chloride plus one mole of water.
The reaction between sulfuric acid (H2SO4) and zinc oxide (ZnO) forms zinc sulfate (ZnSO4) and water (H2O) as products.
Copper carbonate + sulphuric acid = copper sulphate + water + carbon dioxide
oxygen
Get copper suphate + carbon dioxide + water + residual of the original component not in the proper proportion.
Copper oxides are Cu2O - copper(I) oxide and CuO - copper(II) oxide.
Copper plus oxygen react to form copper oxide. This reaction can be represented by the chemical equation: 4Cu + O2 → 2Cu2O.
Oxide is not an element . Copper plus oxygen eaquals copper oxide .Pure copper exposed to oxygen turns greenish .
which salt is produced when hydrochloric acid and ammonium hydroxide
Sulfuric acid plus copper (II) nitrate yields nitric acid plus copper (II) sulfate. Sulfuric acid plus copper (I) nitrate yields nitrous acid plus copper (I) sulfate.
