Calculate the final temperature of a mixture of 200.0g of ice initially at -16.5 Celsius and 406.0g of water initially at 84.5 degrees Celsius.

    q1 = heat to raise temperature of ice from -16.5 C to zero C.
    q1 = mass ice x specific heat ice x (Tfinal-Tinitial)

    q2 = heat to melt the ice.
    q2 = mass melted ice x heat fusion

    q3 = heat to raise temperature of melted ice from zero C to final T.
    q3 = mass melted ice x specific heat water x (Tfinal-Tinitial)

    q4 = heat released by warm water at 84.5 C when lowered to final T.
    q4 = mass warm water x specific heat H2O x (Tfinal-Tinitial)

    Substitute for each of the above and set to zero as
    q1 + q2 + q3 = 0
    and solve for Tfinal.
    Post your work if you get stuck.
