Question
Consider the reaction of Lithium with water:
2 Li(s) + 2H2O(l) ----> 2 LiOH(aq) + H2(g)
The delta H of the reaction is -160 KJ
The enthalpy of fusion of H2O is 6.0 kJ/mol
The specific heat capacity of H2O(l) is 4.18 J/gC
When 10 grams of Li(s) is dropped in a container containing ice and liquid water at 0 degrees Celsius, how many grams of ice will melt?
A) 78.5 g
B) 350 g
C) 19.3 g
D) 700 g
