Asodium ion, na+, with a charge of 1.6×10−19c and a chloride ion, cl− , with charge of −1.6×10−19c, are separated by a distance of 1.1nm. how much work would be required to increase the separation of the two ions to an infinite distance?

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

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
