Consider the five individual ions two cations as well as three anions that come together to form the compound ferric oxide. How many total electrons does each of the cations have?
Calculate the change of entropy for the water, ΔS water, and for the surroundings, delta S surroundings, when 1.00 mole of water freezes at 0 degrees C and the surroundings are at (a) 0 degrees C, (b) -2 degrees C. Explain the physical origin of t..
A solution is prepared by dissolving 246 g of sucrose (C12H22O11) in 624 g of water. What is the vapor pressure of this solution at 30°C? (The vapor pressure of water is 31.8 mmHg at 30°C.)

Suppose that a hotplate transfers 325KJ of energy to 450g of liquid water at 20C. What mass of the water would be boiled away
The net potential energy EN between two adjacent ions is sometimes represented by the expression: EN = -(C/r) + D exp(-r/p) in which r is the interionic separation and C, D, and p are constants whose values depend on the specific material.
