The chemical formula of cupric oxide is CuO.
Both oxidation and reduction
Yes, that is correct. When copper carbonate (CuCO3) is heated, it decomposes into copper(II) oxide (CuO) and carbon dioxide (CO2).
CuO + 2HCL - CuCl2 + H2O
copper oxide.......CuO
fe+3=..............* .9 =fe+2
A. Fe^2+ ==> Fe^3+ + e- is an oxidation reactionB. Fe^3+ +e- ==> Fe^2+ is a reduction reactionC. Fe(s) ==> Fe(l) is neither an oxidation nor a reduction reaction. It is a phase change.D. Fe + 2e- ==> Fe^2+ is not a possible reaction.

1 mole CuO = 79.5454g CuO 3.2g CuO x 1mol CuO/79.5454g CuO = 0.040 mole CuO

This is the ion Fe(3+).
It's a simple acid-base reaction, your acid being your 2HCl and your base being CuO. Acid-base reactions form water, leaving behind a salt (CuCl2).
The chemical formula of cupric oxide is CuO.
3FeO4 + 8Al --> 3Fe + 4Al2O3
