Energy is released by the reaction of hydrazine, N2H4(l), with dinitrogen tetroxide, N2O4(g), according to the unbalanced reaction below. One of the earliest uses was on the Titan family of rockets, used originally as ICBMs, and then as launch vehicles for many spacecraft. Then it was used on the U.S Gemini and Apollo spacecraft and also on the space shuttles to orient and maneuver spacecraft and to propel rockets into space.

- Balance the equation --N2H4(l) + --N2O4(g)= --N2(g) + --H2O(g)

1a. How many grams of H2O can be prepared from 100.0 g of N2H4(l) when it is reacted with excess N2O4(g)? N2H4(l)= 32.05g/mol, N2O4=92.02g/mol, H2O=18.016g/mol, N2=28.02g/mol

1b. How many grams of H2O can be produced from 100.g of N2H4 when it is reacted with 150.g of N2O4? Use the result in 1a to help answer this. Give the limiting reactant and theoretical yield. N2H4=32. 05g/mol, N2O4=92.02g/mol, H2O=18.016g/mol, N2=28.02g/mol

Limiting reactant--------------- grams of H2O----------------

1c. How many grams of the excess reactant remain after reaction has ceased?

Excess reactant------------------ grams remaining------------------

1d. A student obtains 97.7g H2O. What is her percent yield?
