Define how to calculate the final temperature

Reference no: EM13498378

A 0.250 gram chunk of sodium metal is cautiously dropped into a mixture of 50.0 grams of water and 50.0 grams of ice, both at 0 degress celsius. The reaction is

2Na(s)+2H2O(l) yields 2NaOH(aq)+H2(g) Change in H is -368 KJ

Will the ice melt? Assuming the final mixture has a specific heat capacity of 4.18 J/g*degrees celsius, calculate the final temperature. The enthalpy of fusion for ice is 6.02 KJ/mol.
