This question has multiple parts. Work all the parts to get the most points. A soluble salt, MX2, is added to water in a beaker. The equation for the dissolving of the salt is: MX2 (s) - M²+ (ag) + 2X (aq); ΔΗ<0 a Immediately after the salt dissolves, is the solution warmer or colder? warmer colder Correct Since AH is negative, the reaction is exothermic, and the solution will be warmer. b Indicate the direction of heat flow, in or out of the beaker, while the salt dissolves. O in the beaker O out of the beaker
