change to balanced chemical equations copper metal (s) + sulfur (l) - copper (I) sulfide (s) Here’s the best way to solve it.
Solution 1: Formation of. When a solution of copper (II) chloride, CuCl2, is added to a solution of potassium sulfide, K2S, a black precipitate. of copper (II) sulfide, CuS, forms. Write the reaction that forms copper (II) chloride, potassium sulfide, the. complete reaction, and the balanced net ionic equation for the mixture of the two solutions.
When copper (I) sulfide is partially roasted in air (reaction with O 2), copper (I) sulfite is formed first. Subsequently, upon heating, the copper sulfite thermally decomposes to copper (I) oxide and sulfur dioxide. Write balanced chemical equations for these two reactions. There are 2 steps to solve this one. Solution. Share Share. Answered by.

When copper is heated with an excess of sulfur, copper(I) sulfide is formed. In a given experiment, 1.50 g of copper was heated with excess sulfur to yield 1.76 g copper(t) sulfide. What is the percent yield? 27 > 2 points
In MatLab: Dissolution of copper sulfide in aqueous nitric acid is represented by the following chemical equation:where the coefficients a, b, c, d, e, f, and g are the numbers of the various molecules participating in the reaction. These coefficients are unknown and are determined by balancing each atom on the left and right ...
Chemistry questions and answers. The addition of copper nitrate,Cu (NO3)2 to sodium sulfide, Na2S, results in the formation of the “very insoluble” copper sulfide (Ksp = 8 × 10–34). What is the formula of copper sulfide?
Here’s how to approach this question. Identify the molecular formula of each reactant and product in the reaction: Copper sulfide (CuS) reacts with silver nitrate (AgNO_3) to form copper (II) nitrate (Cu (NO_3)_2) and solid silver sulfide (Ag_2S). the balanced reaction is CuS + 2AgN03 ----> Cu (N03)2 ----> Ag2S oxidation number of Cu is +2 ...
