Is Cu oxidized or reduced in CuO plus H2 yields Cu plus H2O?
Cu is oxidized. The oxidation number goes from 0 in Cu to +2 in CuSO4. S is reduced. The oxidation number goes from +6 in H2SO4 to +4 in SO2. The oxidizing agent is H2SO4 since it causes Cu to be oxidized. The reducing agent is Cu since it causes S in H2SO4 to be reduced.
Which of these metals has the hardest oxidation Cu Al Fe or Cr?
Cu
Is cooper a metal or a non metal?
Yes, it is. It shows two oxidation states: Cu(I) and Cu(II).
What is the oxidation number of HClO?
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
The reaction CuO plus CO yields Co2 plus Cu is an example of oxidation or reduction or both or neither?
Both oxidation and reduction
What is the oxidation number in Cu2S?
Cu = +1
What does the oxidation number of an element tell you?
The oxidation number tells you the "combining power" of that element. For example, if Cu has a 1+ oxidation number then it will combine with Cl in a 1:1 ratio, and result in CuCl. If Cu has an oxidation number of 2+, then it will combine with Cl in a 1:2 ratio, and result in CuCl2.
What is the oxidation number of CuF2?
Cu is +2 and F is -1
What are the oxidation numbers of copper CuCl?
Oxidation number is the charge per atom in a compound. Cl2= 2- (Cl= 1-) Cu would have to be 2+ to balance the compound, because there is only one copper atom.
What is oxidation number of Cu?
If the question is Cu2, then it is equivalent to Cu and the oxidation number for any element is zero. If the question is Cu2+, then the oxidation number is +2.
What is the oxidation number of CuFeS2?
cu =1+ fe=3+ s=2-
What is the oxidation number of cuco3?
+2 for Cu, +4 for C, -2 for O
Is Cu oxidized or reduced in CuO plus H2 yields Cu plus H2O?
Cu is oxidized. The oxidation number goes from 0 in Cu to +2 in CuSO4. S is reduced. The oxidation number goes from +6 in H2SO4 to +4 in SO2. The oxidizing agent is H2SO4 since it causes Cu to be oxidized. The reducing agent is Cu since it causes S in H2SO4 to be reduced.
Which of these metals has the hardest oxidation Cu Al Fe or Cr?
Cu
What is the oxidation number of CuHSO4?
+1 for Cu, +1 for H, +6 for S, -2 for each O
What is the redox equation for the oxidation of copper iodide?
Cu ----> Cu 2+ + 2e-
What is the oxidation half reaction of Cl2 2Cu to 2CuCl?
Cl2 + 2Cu --> 2CuCl Oxidation reaction is Cu --> Cu+ + 1e Reduction reaction is Cl + 1e --> Cl- Redox reaction is Cu + Cl --> Cu+ + Cl-
