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

How many kilograms of copper sulfide could be formed from reaction of 0.90mol of copper with excess sulfur?
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!
What is the chemical formula for copper 1 sulphide?
Cu2S
Maxium amount of Cu2s that can be formed if 42.35g Ni2S3 reacts with 66.01g CuNO3?
4.63g is the maximum amount of Cu2s that can be formed if 42.35g Ni2S3 reacts with 66.01g CuNO3.
What is the chemical formula for cupric sulfide?
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)
What is the chemical formula for copper plus sulfur?
Copper sulfide. Depending on the valence of copper, you could have CuS or Cu2S
Why is extraction of copper termed as auto reduction?
Asker: "Is it because during roasting, the sulphide ore (Cu2S) gets converted to its metallic oxide (Cu2O) and SO2 gas?"

What are the formulas for copper1oxide nantokite copper1 chloride and chalcocite copper1 sulfide?
Copper(I) oxide - Cu2O - is the mineral cuprite.Copper(I) chloride - CuCl - is the mineral nantokite.Copper(I) sulfide - Cu2S - is the mineral chalcocite.
What is the equation Copper reacts with sulfur giving cuprous sulphide?
This equation is basically 2Cu + S => Cu2S. If it was cupric sulfide it would be Cu + S -----> CuS
What is the molecular equation of CuNO32and NaS2?
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).

What is the balanced equation for copper an oxygen?
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
What is the oxidation number in Cu2S?
Cu = +1
