What is the oxidation number of the copper in CuNH33Cl-NO3?
The oxidation number of copper in CuNH3Cl2NO3 is +1. This is because the overall charge of the complex ion is -1, and the oxidation numbers of N, H, Cl, and O remain the same as their typical values, leaving copper with a +1 oxidation state to balance the charge.

What is the copper-to-sulfate ratio in copper(I) sulfate?
Copper(I) sulfate is Cu2SO4: the ratio Cu/SO4 is 2.
What is the formula for copper (I) bicarbonate?
Copper II Bicarbonate is Cu(HCO3)2 and Copper I Bicarbonate is CuHCO3
Do copper isotopes have a whole atomic mass?
The isotopes of copper have the relative atomic masses of 63 and 65 and these are approximations. The exact values contain decimal figures.
When copper conbines with oxygen to form copper oxide the charge of the copper ion is?
+2
When copper combines with oxygen to form copper oxide the charge of the copper ion is?
When copper combines with oxygen to form copper oxide, the copper ion has a +2 charge. This is because copper typically forms a 2+ oxidation state when it combines with oxygen in this compound.
What is the formula for copper II bicarbonate?
The chemical formula for copper(II) bicarbonate is Cu(HCO3)2.
What do the roman numerals mean in Copper II?
The Roman numeral II in Copper II denotes the oxidation state of copper, which is +2. This indicates that copper in the compound has lost two electrons and has a 2+ charge.
Copper plus chlorine?
When copper reacts with chlorine, copper chloride is formed. The balanced chemical equation for the reaction is: 2 Cu + Cl₂ → 2 CuCl
What is the chemical formula for Copper Perchlorate?
If it's copper (I): CuClO4 If it's copper (II): Cu(ClO4)2
