Cu+ S2-
what name does that make an how do you solve it? is it CuS2 copper sulfide?
,
Yes, you are correct! The compound Cu+ S2- is named copper sulfide. To solve it, we need to balance the charges of the ions involved.
Since Copper (Cu) has a charge of +1 and Sulfur (S) has a charge of -2, we need one Copper ion to balance the charge of two Sulfur ions. Therefore, the formula of the compound is CuS.
Please note that CuS, with a subscript of 2, would indicate two copper atoms bonded with one sulfur atom, and it does not accurately represent the charge balance between Cu+ and S2-. So, the correct formula is CuS, without any subscript.
Yes, Cu+ and S2- combine to form copper sulfide, which has the chemical formula CuS. To determine the name and formula, you need to understand the charges of the ions and use the principle of charge neutrality.
Cu+ means the copper ion has a +1 charge, indicating it has lost one electron. S2- means the sulfide ion has a -2 charge, indicating it has gained two electrons.
To form a neutral compound, the charges of the ions must balance out. In this case, one copper ion (Cu+) with a +1 charge combines with one sulfide ion (S2-) with a -2 charge. These charges cancel each other out, resulting in a neutral compound.
Therefore, the formula of the compound formed is CuS, and the name of the compound is copper sulfide.
When you have an element with different ions, you have to specify with Roman numerals which ion you're using when naming it. Copper has multiple charges, so you will have to specify which ion of copper you're using: Cu^+ is copper(I) and Cu^2+ is copper(II)
copper(I) has a charge of 1+. Sulfur has a charge of 2-. You need one more positive ion to cancel out the negative, so the answer is Cu2S
