how many joules of energy must be removed from 325g water at 35 degress celsius to form ice at 0 degress celsius?

  • chemistry -

    q1 to remove T from 35 to zero.
    q1 = mass H2O x specific heat x (0-35)

    q2 = heat to remove energy to freeze the water.
    q2 = mas H2O x heat fusion.

    Total Q = q1 + q2.
