Chalcocite is an ore from which copper can be extracted for commercial use. the formula for this important ore is cu2s. in the laboratory it is formed by the following reaction: 2cu s → cu2s the reaction takes place in laboratory conditions that allow the reactant atoms to move freely about in the reaction vessel. explain this reaction in terms of collision theory.

Respuesta :

 2 moles of Cu atoms are mixed with 1 mole of S atoms. you have to heat or stir allowing for the atoms to collide. when 2 Cu atoms collide with 1 S atom, Cu2S is formed. unfortunately, it isn't that easy because adding copper and sulfur together without a catalyst or in solution would not produce copper I sulfide. You need to create an environment for a redox reaction to occur. most likely acidic conditions.

Effective collisions between molecules of copper (ii) sulphide are required for the formation of copper(i) sulphide in the laboratory.

What is the collision theory?

The collision theory states that chemical reactions occur only when there are effective collisions between reactant molecules.

Effective collisions are collisions in which the reactants molecules collide with energy equal to or greater than the activation energy of the reaction.

In the formation of copper(i) sulphide from copper (ii) sulphide, the reactant molecules must first collide with energy equal to or greater than the activation energy to break reactant bonds before formation of the bonds in the products.

Therefore, effective collisions between molecules of copper (ii) sulphide are required for the formation of copper(i) sulphide in the laboratory.
