What is the formula for copper (l) sulfide? - Socratic
2018年5月26日 · "Copper(I) sulfide"-="cuprous sulfide"-=Cu_2S Copper metal can access two common oxidation states, i.e. Cu^+ or Cu^(2+): underbrace(Cu_2S)_"copper(I) sulfide or cuprous sulfide"; underbrace(CuS)_"copper(II) sulfide or cupric sulfide". As are most sulfide salts, both salts would be as soluble as bricks in aqueous solution, and are poorly characterizable...

What is the formula for copper (I) sulfide? Chemical Bonds: An ionic chemical bond is when oppositely charged electrons bond with each other, which can create a new compound.
How can I calculate the empirical formula of copper sulfide?
2015年1月10日 · In order to determine the empirical formula for copper sulfide (or for any compound, for that matter) you need to have some information about either the mass of one reactant and the mass of the product, or about the percent composition of the copper sulfide. For the first case, let's assume you are doing a lab experiment in which you heat a mixture of …
What is the salt formed when Copper (II) combined with ... - Socratic
2018年3月12日 · Copper(II) sulfide. This is copper and sulfur reacting to form copper(II) sulfide. Copper forms an ion with 2+ charge. Sulfur forms an ion with 2- charge, so the formula of copper(II) sulfide is "CuS" as the charges simply cancel out.
What is the empirical formula for copper sulfide?
The empirical formula for copper sulfide is CuS. To find the empirical formula for copper sulfide, we ...
What is the name of Cu_2S? - Socratic
2017年1月30日 · Copper sulfide or dicopper sulfide Copper has two common oxidation numbers + 1 and +2. Sulfur has a common oxidation number of -2 A more precise name would be Copper I sulfide. A common name would be Cuprous sulfide. This is an old name for compounds with a +1 charge on Copper. Cupric Sulfide would have the formula CuS with a +2 charge on Copper.
Copper will react with sulfur to form a copper sulfide, if 1.500g ...
2015年10月29日 · "Cu"_2"S" The idea here is that you need to use the mass of copper and the mass of the copper sulfide to determine how much sulfur the produced compound contains, then convert these masses to a mole ratio. So, assuming that sulfur is in excess, you know that all the number of moles of copper that reacted will now be a part of the copper sulfide. This mens that …
