Solid KF has a lattice energy of 804 kJ/mol and a heat of solution (in water) of -15 kJ/mol. RbF has a lattice energy of 768 kJ/mol and a heat of solution (in water) of -24 kJ/mol. Which salt forms stronger attractions with water

the dissolution of polymer can be thermodynamically described in 2 steps.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.

the answer is barium and copper bromide

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
