q1 = heat needed to raise T from 50 C to 100 C.
q1 = mass H2O x specific heat liquid H2O x (delta T)-----delta T = Tfinal-Tinitial = 100-50 = 50
q2 = heat needed to vaporize liquid H2O at 100 C to vapor(steam) at 100 C.
q2 = mass H2O x heat vaporization.
q3 = heat needed to heat steam at 100 to steam a 120 C.
q3 = mass steam x specific heat steam x delta T----120-100 = 20
Total q needed = q1 + q2 + q3.
How much heat is needed to cause the following irreversible reaction?
200 g of liquid H2O at 50°C is heated to form 200 g of steam at 120°C
