When I was a freshman in high school, the teacher dictated the chemical equation. What I wrote was cu＋s=heating=cus. The teacher said, wrong, it should be 2cu+s=heating=cu2s. Then I searched on Baidu. [Picture] The teacher said... Show all Followers 5 Viewed The analysis of Cus is correct. Starting from the valence bond and analyzing the oxidation number can explain the problem better. It is not a molecule, so doubling the simplest formula based on the unit cell structure makes no sense. Tetrasodium tetrachloride is unpleasant to listen to. Regarding average price, according to electronegativity, microscopic view, right. H2s + cuso4 = cus↓ + h2so4 h2s + pb (no3)2 = pbs↓ + 2hno3 (When hydrogen sulfide is detected with lead nitrate, this reaction can be considered to have occurred) The common reason why the above two reactions can occur is that the solubility is extremely low.

It does not violate that the production of a weak acid by a strong acid is only an applicable rule in a simple hydrogen ion transfer reaction. Common examples of "weak acid to strong acid" include precipitation (such as c u s ), the generation of gas (such as concentrated phosphoric acid evaporating h c l ) and leaving the reaction system; or the occurrence of oxygen. Copper sulfide is a compound of copper and sulfur with the chemical formula cus, which occurs in nature as dark blue indigocite. It is a moderately conductive conductor. When hydrogen sulfide gas is passed into a copper salt solution, a colloidal precipitate of copper sulfide can be formed. There is currently research and development.
