Question

Imagine that a full 500 mL bottle of water (d = 0.9998 g/mL) sitting in your car during the summer went from 15.0 degree C to 20 degree C. Assuming that the same amount of energy went into a 150.0 gram seatbelt (S_h = 0.85 J/(g K)) what would the temperature be in Celsius, if the seat belt was originally at 18 degree C? Write the reaction for the enthalpy of formation reaction of iron (III) dichromate. Calculate the enthalpy of the reaction for the reduction of nitrate to ammonia as shown below. Be sure to balance the equation, and use Appendix C at the back of the text to locate the values._NO_2(g) +_H_2(g) rightarrow_NH_3(g) +_H_2O(g)
