15 g of a salt is dissolved in 150 mL of water, which resulted in the temperature of the water going up by 7 C. What is the energy released/absorbed by the water? (report in kJ) (include the mass of the salt in your calculation) (specific heat of water 4.18 J/gK)

Compare the equilibrium constants for the systems shown in the table. which favors products the most? which favors products the least? rank these systems in order from most to least in terms of favoring products rather than reactants. d > b > a > c c > a > b > d b > c > d > a a > d > c > b
