'2Cu; is two molar ratios of copper.
The word equation for the reaction 2Cu + O2 -> 2CuO is: Copper + Oxygen -> Copper(II) oxide.
The balanced equation for the corrosion of copper is: 2Cu(s) + O2(g) + H2O(l) + 2e- -> 2Cu2+(aq) + 2OH-(aq)
When copper is heated in air, it undergoes oxidation to form copper(II) oxide. The chemical equation for this process is: 2Cu(s) + O2(g) → 2CuO(s)
A substance doesn't have any kind of equation. Do you mean the chemical name in words? Verdigris is not a specific compound, but an indeterminate name for the coating which forms on weathered copper, which may be considered as basic copper carbonate, or for the impure copper acetate used as a pigment.
The balanced equation for the reaction between Cu(NH3)4 and K4Fe(CN)6 is: 2Cu(NH3)4 + K4Fe(CN)6 -> Cu2Fe(CN)6 + 8NH3 + 4KCN
what is 2CU
When copper is heated in air, it reacts with oxygen to form copper oxide. The equation for this reaction is: 2Cu(s) + O2(g) -> 2CuO(s)
The word equation for the reaction 2Cu + O2 -> 2CuO is: Copper + Oxygen -> Copper(II) oxide.
2Cu (s) + O2 (g) -----------------> 2CuO (s)
2Cu+O2 ---> 2CUO
The final answer would be 2Cu O2---> 2CuO
Oxidation
2Cu(NO3)2(s)+heat------->2CuO(s)+4NO2(g)+O2(g)
I think: (NH4)2Cu(SO4)2
SO4H2 + 2Cu --> SO2 + 2CuOH
2Cu(s) + O2(g) --> 2CuO(s)
Cl2 + 2Cu --> 2CuCl Oxidation reaction is Cu --> Cu+ + 1e Reduction reaction is Cl + 1e --> Cl- Redox reaction is Cu + Cl --> Cu+ + Cl-
