17.5 kj of heat is required to melt 52.5g of ice at its melting point. How much heat is required to raise the temperature of 52.5g of water from its melting point to its boiling point? express answer in kj.
A pure silver ring contains 2.80 x 10^22 silver atoms. How many silver atoms does it contain. Please show your steps and solutions.
Given that Delta H (fusion) of water is 6025 J/mol, Cp(ice) = 37.7 J/K mol, and Cp(water,liquid) = 75.3 J/K mol, calculate Delta G (in J) for the freezing of 54 moles of water at 1 atm pressure and the constant temperature T =13.1 C.
