Cu2S + O2 ---> Cu2O + SO2
On the left hand side we count up all the individual atoms:
Cu = 2
S = 1
O = 2
On the right hand side we do the same:
Cu = 2
S = 1
O = 3
Notice we have one extra O atom on the right? To fix that we would have to have 11/2 O2 on the left hand side.
Cu2S + 11/2O2 ---> Cu2O + SO2
Because you can't use fractions when balancing equations, we double the whole equation, resulting in a balanced equation with no fractions.
2Cu2S + 3O2 ---> 2Cu2O + 2SO2
First, the category you chose for this question is way off...but ill answer it. i believe its Cu2O plus C yields Cu2 plus CO.
2Cu + O2 -> 2Cu2O
2Cu2S + 3O2 --> 2Cu2O + 2SO2
First you need to write a balanced chemical equation: 2Cu + S >> Cu2S Then you use dimensional analysis to solve and convert to kilograms: 0.90 mol Cu x 1 mol Cu2S/2 mol Cu x 159.166g Cu2S x 1kgCu2S/10^3g Cu2S= 7.2 x 10^-2 kg Cu2S Hope this helps!
Cu2S
4.63g is the maximum amount of Cu2s that can be formed if 42.35g Ni2S3 reacts with 66.01g CuNO3.
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
Asker: "Is it because during roasting, the sulphide ore (Cu2S) gets converted to its metallic oxide (Cu2O) and SO2 gas?"

Copper(I) oxide - Cu2O - is the mineral cuprite.Copper(I) chloride - CuCl - is the mineral nantokite.Copper(I) sulfide - Cu2S - is the mineral chalcocite.
This equation is basically 2Cu + S => Cu2S. If it was cupric sulfide it would be Cu + S -----> CuS
For the molecular balance of the equation it would be: CuSO4 (aq) + Na2S (aq) = CuS (s) + Na2SO4 (aq). For the net ionic balance of the equation it would be: Cu2+ (aq) + S2(aq) = CuS (s).

There are two different copper oxide formula's:2Cu + O2 -> 2CuO (black Copper(II) oxide)or4Cu + O2 -> 2Cu2O (red Copper(I) oxide)Copper(II) = Cu2+Oxide = O2-CuO or copper(II) oxide
Cu = +1
Copper sulfides describe a family of chemical compounds and minerals with the formula CuxSy. Prominent copper sulfide minerals include Cu2S (chalcocite) and CuS (covellite).
