In a magnesium oxide unit, the distance between the magnesium ion (Mg2+) and the oxide ion (O2−) is 2.13×10-10 m. Calculate the work required to separate the two ions to an infinite distance apart. (Model the ions as point charges at rest before and after the separation.) If you could do this without using Calculus that would be great.

In a magnesium oxide unit, the distance between the magnesium ion (Mg2+) and the oxide ion (O2−) is 2.07×10-10 m. Calculate the work required to separate the two ions to an infinite distance apart. (Model the ions as point charges at rest before and after the separation.)
In a magnesium oxide unit, the distance between the magnesium ion (Mg2+) and the oxide ion (O2−) is 1.81×10-10 m. Calculate the work required to separate the two ions to an infinite distance apart. (Model the ions as point charges at rest before and after the separation.)
A magnesium ion, Mg2+, with a charge of 3.2×10−19C and an oxide ion, O2−, with a charge of −3.2×10−19C, are separated by a distance of 0.40 nm. How much work would be required to increase the separation of the two ions to an infinite distance?
In a potassium chloride unit, the distance between the potassiumion (K+) and the chloride ion (Cl-) is2.80 10-10 m.(a) Calculate the energy required to separatethe two ions to an infinite distance apart. (Model the two ions astwo point particles initially at rest.)1 eV(b) If twice the energy determined in Part (a) is actuallysupplied, what is the total amount of kinetic energy that the twoions have when they were an infinitedistance apart?2 eV
Model I: The Dissolution of Magnesium Hydroxide in Water When solid Mg(OH)2 dissolves in water, the chemical reaction is: Mg(OH)2(s) Mg2+(aq) + 2OH-(aq) (1) Table I. These are the results after equilibrium has been established for the addition of solid Mg(OH)2(s) to water yielding a final volume of 10.0 L of solution. Total amount of Mg(OH)2 added Mg2+ concentration in the resulting solution at eq OH- concentration in the resulting solution at eq Mass of Mg(OH)2 that does not dissolve...
1. The headlights on an automobile are 125 cm apart. At what distance will the lights appear to be just resolvable to a person whose nocturnal pupils are 4.5 mm in 2. Assume the range of pupil variation during adaptation of a normal eye is from 2.0 to 7.1 mm. What is the corresponding range of distances over which it can detect 3. Two stars make an angle of 1 x 10-3 radians at the eye of an observer. A...
1. In class, we calculated the electrostatic force between sodium and chlorine ions in NaCl, which is an example of an ionic bond Another type of chemical bond is a covalent bond, where electrons are shared between atoms, like in a hydrogen molecule, H2. We can try to model this as a collection of three charges, with the two nuclei treated like two +e charges, and the two electrons treated as one -2e charge. (20 points) If the electrons are...
What is the difference in between conductor and insulators? Write with necessany figures and examples of electrostatic charging by Induction? What is conservation of Charge? 1. Problem-1: Find the charge (Q) of a system having 1000 electrons? Explain the electric field produced due to a positive and negative point charges separately with necessary figures? 2. Problem-2: Calculate the electricfield (E) at a field point of 0.2 μm from a point charge q 10 pC? 3. What is electric dipole moment?...

Why wouldnt a weak base, such as NH3, work just as well as KOH
in (1)?
2.2 Is the question I have. I figured out
2.1 already.
Below is relevant info. Thanks!
2. (1) Describe how adding a solution of KOH to the original sulfide precipitate results in the separa- tion of Sn4+ ion from the other Group W cations. (2) Why wouldn't a weak base, such as aque- ous NH3, work just as well as aqueous KOH in (1)?...
