Answer:
Explanation:
Due to Coulomb´s law electric force can be described by the formula , where K is the Coulomb´s constant (), = Charge 1 (Na+ in this case), is the charge 2 (Cl-) and r is the distance between both charges.
Work made by a force is W=F.d and total work produced is the change in energy between final and initial state. this is .
so we have
Given that ri= 1.1nm= and rf= infinite distance
Answer:
Practice good personal hygiene. Wash your hands after removing gloves, before leaving the laboratory, and after handling a potentially hazardous material. While working in the laboratory, wear personal protective equipment - eye protection, gloves, laboratory coat - as directed by your supervisor.
