Cu^+ + Cu^+ + S^2- where the S has 8 electrons surrounding it (4 lone pairs). Very difficult to draw dot structures on this site.
x Cu x
the x's stand for the dots.
Copper has two electrons in the outter most energy level.
used as algaecide .
Copper(I) sulfide is Cu2S Copper(II) sulfide is CuS
The formula for copper(II) sulfide is CuS the formula for copper(I) sulfide is Cu2S.
Cu2S is copper(I) sulfide
Copper sulfate has CuSO4 as its formula. Copper sulfate is also written copper(II) sulfate. Remember that Copper sulfate contains Copper, Sulfate and Oxygen because anything ending with 'ate' therefore contains oxygen
Cu(I) sulfide has the formula Cu2S. Thus the mass in grams of a single formula unit is 63.5 x 2 = 127 for two coppers32.1 x 1 = 32.1 for one STotal = 159.1
Copper(I) sulfide is Cu2S Copper(II) sulfide is CuS
There is copper (I) sulfide, with the formula Cu2S, and there is copper (II) sulfide with the formula CuS.
The formula for copper(II) sulfide is CuS the formula for copper(I) sulfide is Cu2S.
Cu2S is copper(I) sulfide
Copper sulfate has CuSO4 as its formula. Copper sulfate is also written copper(II) sulfate. Remember that Copper sulfate contains Copper, Sulfate and Oxygen because anything ending with 'ate' therefore contains oxygen
copper (I) sulfide Common name: Chalcocite. It is an important copper mineral ore that is opaque with a dark grey to black luster.
The formula for cuprous sulfide is Cu2S. Copper (I) or cuprous has a +1 charge, whereas Sulfur has a charge of -2. Cu^(-1) + S^(-2) -> Cu2S (The subscript is 2)
Copper sulfide. Depending on the valence of copper, you could have CuS or Cu2S
Chalcocite is a copper(I) sulfide (Cu2S), an important copper ore mineral
The formula for cuprous sulfide is Cu2S. Copper (I) or cuprous has a +1 charge, whereas Sulfur has a charge of -2. Cu^(-1) + S^(-2) -> Cu2S (The subscript is 2)
Solid copper reacts with solid sulfur to form Copper(I) sulfide. 2Cu(s)+S(s) -> Cu2S(s)
2Cu(s)+S(s)→Cu2S(s)
