Acalorimeter contains 500 g of water at 25°c. you place a hand warmer containing 100 g of liquid sodium acetate (naac) inside the calorimeter. when the sodium acetate finishes crystallizing, the temperature of the water inside the calorimeter is 32.2°c. the specific heat of water is
4.18 j/g-°c. what is the enthalpy of fusion (δhf) of the sodium acetate? show your work.

What is the equilibrium constant of aa+bb=cc+dd

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
