  1. Your nonuse of units on the heats is disappointing. I am going to guess they are in J/kg, even in that, they are rouned loosely.
    The sum heat changes = zero.
    -massice*2100J/kg-massice*336000J/kg -(massice)4200(10-0)+200(4200)(25-10)=0

    check that. Negative means heat absorbed, positive means heat given off.
