The pictures show two different ways H2 and O2 can be reacted together according to the following equation. A measurement was made and it was found that for every mole of reaction occurring in the space shuttle engine 97 kJ of work was done to propel the space shuttle and 196 kJ of heat was lost. In the fuel cell only 35 kJ of heat was lost. What is the value of w for the fuel cell? A. -293 kJ В. 293 kJ C. -258 kJ D. 258 kJ E. cannot answer with information provided
