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!

Is sodium sulfide plus copper sulfate equals copper sulfide percipitate?
Yes: If aqueous solutions of copper sulfate and sodium sulfide are mixed, copper sulfide will precipitate from the mixture.
Solid copper reacts with solid sulfur to form solid copper I sulfide?
Solid copper reacts with solid sulfur to form Copper(I) sulfide. 2Cu(s)+S(s) -> Cu2S(s)
Can copper and sulfur combine into a compound?
Yes, they combine to form Copper Sulfide.
What is the chemical formula for copper plus sulfur?
Copper sulfide. Depending on the valence of copper, you could have CuS or Cu2S
In what form is copper found in nature?
Occasionally as elemental copper but more often as a sulfide or an oxide.
What is the chemical formula copper sulfide?
Copper(I) sulfide is Cu2S Copper(II) sulfide is CuS
What is the correct name for CuS?
CuSO4 copper sulfateCuSO3 copper sulfiteCuS copper sulfideCuSO unknown, rather impossible copper-sulfur compound
When copper and sulfur combine to form copper sulfide?
There is copper (I) sulfide, with the formula Cu2S, and there is copper (II) sulfide with the formula CuS.
What is the chemical formula for copper (II) sulfide?
The formula for copper(II) sulfide is CuS the formula for copper(I) sulfide is Cu2S.
Is sodium sulfide plus copper sulfate equals copper sulfide percipitate?
Yes: If aqueous solutions of copper sulfate and sodium sulfide are mixed, copper sulfide will precipitate from the mixture.
What is the name of the compound with the formula Cu2S?
copper (I) sulfide Common name: Chalcocite. It is an important copper mineral ore that is opaque with a dark grey to black luster.
What best explains this reaction Cu2S plus O2 equals 2Cu plus SO2?
Copper sulfide reacts with exces oxygen to produce copper and sulfur dioxide. This could be in the industrial production of copper from copper ores.
What is the chemical formula for copper 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
