A winter skier made a hand warmer by placing 1.0 mol of sodium acetate, NaCH3CO2 (molar mass = 82.03 g/mol), in a plastic wrap pouch within a container of water. The skier then opened the plastic wrap pouch, allowing the sodium acetate to
mix with the water. This formed a 500 g solution with a temperature change of 27°C. What is the heat of solution given the
specific heat of water is 4.18 J/g.°C?
O A. 6.57 x 104 J/mol
O B. 1.12 x 10² J/mol
O C. 5.64 x 104J/mol
O D. 9.25 x 103 J/mol

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

have a great day because if you dont you and i will be sad
