In the electrolysis of a molten mixture of RbF and SrCl2, identify the product that forms at the negative electrode and at the positive electrode. The cell temperature must be high enough to keep the salt mixture molten hence the metal appears as a liquid and the halogen as a gas. product at the negative electrode (cathode) product at the positive electrode (anode)

Strontium at cathode

chlorine at anode

Explanation:

Please refer to the attached file for a clearer and better detail of how the answer was arrived at.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
