For a k and cl– ion pair, attractive and repulsive energies ea and er, respectively, depend on the distance between the ions r, according to for these expressions, energies are expressed in electron volts (ev) per k –cl– pair, and r is the distance in nanometers. the net energy enet is just the sum of the two expressions above. (a) draw/superimpose on a single plot: enet, er, and ea versus r up to 1.0 nm. (b) schematically determine (i) the equilibrium spacing (bond length) r0 between the k and cl– ions, and (ii) the magnitude of the bonding energy e0 between the two ions. (c) mathematically determine (i) the r0 and (ii) the e0 and compare these with the graphical results from part (b).

Sasha has just gotten a new job in a nearby city. after comparison shopping, she found that renting a nice two-bedroom apartment would cost around $800 per month. her utilities would cost about $150 per month. sasha has enough money saved for a down payment, and she found that she can buy a three-bedroom house or condo with a mortgage payment of $1,000 per month, including taxes and homeowner's insurance. her utilities would cost about $200 per month. what is the advantage of buying the house over renting the apartment?
