2N2H4 + N2O4 ===> 4H2O + 3N2
100/32/2 = 1.5625 moles of N2O4 can be reacted by N2H4
200/92 = 2.174 moles of N2O4 are present
Thus N2H4 is limiting
Grams of N2 = 100/32 moles of N2H4 * (3molesN2/2 moles N2H4) * 28grams N2/mole = 131 grams of N2 can be produced

A fuel mixture used in the early days of rocketry consisted of two liquids, hydrazine (N2H4) and dinitrogen tetroxide (N2O4) which ignite on contact to form nitrogen gas and water vapor. How many grams of nitrogen gas form when 1.00 x 10^2 g of N2H4 and 2.00 x 10^2 g of N2O4 are mixed? So, I tried solving this but not sure what they mean by "mixed". The balanced chemical equation is: 2 N2H4 + N2O4 = 3 N2 +...

Nitrogen dioxide is one of the many oxides of nitrogen (often collectively called "NOX") that are of interest to atmospheric chemistry. It can react with itself to form another form of NOx, dinitrogen tetroxide. A chemical engineer studying this reaction fills a 500. mL flask with 2.6 atm of nitrogen dioxide gas. When the mixture has come to equilibrium she determines that it contains 2.0 atm of nitrogen dioxide gas. The engineer then adds another 0.87 atm of nitrogen dioxide,...

Nitrogen dioxide is one of the many oxides of nitrogen (often collectively called "NOX") that are of interest to atmospheric chemistry. It can react with itself to form another form of NOx, dinitrogen tetroxide. A chemical engineer studying this reaction fills a 5.0 L flask with 4.8 atm of nitrogen dioxide gas. When the mixture has come to equilibrium she determines that it contains 2.6 atm of nitrogen dioxide gas. The engineer then adds another 1.2 atm of nitrogen dioxide,...
