Actually copper has two common oxidation states, +1 and +2. However, we can leave that aside in discussing this question.
If we can assume that various atomic masses are known then a sample of a known mass of cupric oxide could be reduced with a known amount of hydrogen and the products weighed.

Since Oxygen has an ion charge of -2 & Copper has a 2 as a subscript, it means that Copper's ion charge will be +1. Cu2O = Copper (I) Oxide
copper sulfate is CuSO4 and that in itself is neutral because the anion has a charge of -2 and copper has a charge of +2
There is no charge. All compounds are electrically neutral. If you mean the charges of the component ions, copper carries a 2+ charge and the hydroxide ions carry a 1- charge.
A copper ions has a positive charge, most commonly 2+.
Copper can have a +2 oxidation state because it can lose two electrons from its outermost shell to achieve a stable electron configuration. This results in the formation of Cu2+ ions with a charge of +2.
Since Oxygen has an ion charge of -2 & Copper has a 2 as a subscript, it means that Copper's ion charge will be +1. Cu2O = Copper (I) Oxide
It is 1+ charge, but if they say copper (II), then that's 2+ charge.
copper sulfate is CuSO4 and that in itself is neutral because the anion has a charge of -2 and copper has a charge of +2
There is no charge. All compounds are electrically neutral. If you mean the charges of the component ions, copper carries a 2+ charge and the hydroxide ions carry a 1- charge.
Copper sulfate has CuSO4 as its formula. Copper sulfate is also written copper (II) sulfate.
The charge on the copper ion in CuF2 is +2. This is because fluorine typically has a charge of -1, and there are two fluorine atoms in the compound which balances out the charge of the copper ion.
A copper ions has a positive charge, most commonly 2+.
When copper combines with oxygen to form copper (II) oxide, the charge of the copper ion is +2. This is because in copper (II) oxide, each copper ion has lost two electrons to oxygen atoms, resulting in a +2 charge.
The charge of copper (Cu) can vary depending on the specific compound it is part of. In its most common form in nature, copper typically has a charge of +2.
+2
The compound is copper(II) oxide, which has a chemical formula CuO. In this compound, copper is in the +2 oxidation state, giving it a charge of 2+.
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.
