Asked by Joshua
is this the right anser? for this problem please let me know thanks
calculate the amount of heat in kilojoules released when 50 grams of steam at 125 C are converted to 50 grams of ice at -125 C
so
50 grams of H2O
Ti= 124 C
Tf= -125 C
q=? J=?
q=m *Cp * At
J= 50g * 4.184J/g C= (-125 C - 125 C) =2.1 x 10^2 j
is this the right? please let me know thanks

no. I answered this before, and you did not do it the suggested way.
