Calculate the enthalpy change when 50. g of ice at -30.0 °C is heated to completely melt to liquid water at 0.0°C. (The heat of fusion for water is 333 J/g.)

  • chemistry -

    q1 = heat required to raise T of ice from -30 to O C.
    q1 = mass of ice x specific heat ice x (Tf - Ti) where Tf is final T (O) and Ti is initial T (-30).
    q2 = heat required to melt the ice at zero; i.e., change from solid phase to liquid phase.
    q2 = mass of ice x heat fusion.
    total q = q1 + q2.
