The magnitude of the electrostatic force between two identical ions that are separated by a distance of 8.3 × 10-10m is 192.9 × 10-9n.(a)what is the charge of each ion? (b)how many electrons are ""missing"" from each ion (thus giving the ion its charge imbalance)?

(a) 1.215 x 10^-13 J

(b) n = 7.6 x 10^5

Explanation:

distance, r = 8.3 x 10^-10 m

Force, F = 192.9 x 10^-9 N

Let the charge is q.

(a) According to the Coulomb's law

q = 1.215 x 10^-13 C

(b) Let n number of electrons are missing.

n = 7.6 x 10^5

- measure reactants precisely. ( first choice)

- stir to the reaction take place. ( second choice)

- wait patiently until the reaction completes. ( fourth choice)

- make sure to recover as much copper as possible. ( last choice)

they should be similar or the same
