In the book (and movie) The Martian. Mark Watney reduces hydrazine (N_2H_4) with an iridium catalyst in order to produce hydrogen gas a) Write the balanced chemical equation for the standard enthalpy of/or mat ion fox hydrazine. b) If the standard heat of formation of hydrazine is 50.63 kJ/mol, how much heat is released when 1.0000 kg of hydrazine is reduced to hydrogen gas and nitrogen gas? What volume of hydrogen gas is produced at STP?
