In order to determine the lattice formation energy for KCl, the following data are provided: Ionization energy of K(g) = 425 kJ/mol
Electron affinity of Cl(g) = –349 kJ/mol
Energy to sublime K(s) = 89 kJ/mol
Bond energy of Cl2(g) = 240 kJ/mol
ΔHf for K(s) + ½Cl2(g) → KCl(s) = –438 kJ/mol

Sort the steps of the Born–Haber cycle according to the sign of the energy change associated with each.

K(g) → K^(g)+ e
K^+(g) + Cl^- →KCl(s)
K(s) + K(g)

Maria wants to determine which type of disinfectant kills the most bacteria. which of the following is the best way for maria to determine this? a. ask ten different companies that make disinfectants which type is best. b. put the same amount and species of bacteria on ten identical plates, and add ten different kinds of disinfectant to each plate. c. interview ten different people to determine which type of disinfectant they prefer. d. put the same amount and species of bacteria on ten identical plates, and add a different disinfectant to each plate.

Needthe meter is the standard unit for: 1) height 2) length 3) weight 4) mass

The diagram below shows a cell placed in a solution.a cell is shown placed inside a beaker. it is labeled cell. the solution inside the beaker is labeled 40% salt solution and the solution inside the cell is labeled 20% salt solution.only water is allowed to move in and out of the cell. what will most likely happen to the cell? it will expand as water moves out of it. it will shrink as water moves out of it.it will expand as water moves into it. it will shrink as water moves into it.
