15. (10 pts.) Hydrazine (N,Ha) is commonly used as rocket fuel. It reacts with oxygen according to the balanced chemical equation: N2H4(g) + 302(g) + 2N02(g) + 2H20(1) 70.5 g of Hydrazine (N,Ha) is reacted with 195.3 g of Oz to test the thermodynamics of the reaction. MAKE SURE TO SHOW ALL OF YOUR WORK Compound Molecular Weight (g/mol) N2H4 32.06 0 32.00 NOZ 46.01 a. Identify the limiting reactant: b. How many grams of NO, should be produced in...
Hydrazine, N2H4 has literally been used as rocket fuel. It reacts exothermically with oxygen as shown below: AH=-577 N2H4 (8) + O2(g) →N2 (g) + 2 H2O(g) kJ/mol What quantity of heat is released when 1.00 kg of hydrazine is combusted? 18.0 kJ 6 5.70 x 105 kg 0 1.80 x 10 kg
