A 58.3g sample of NH3 is reacted with 126g O2, according to this reaction what is the limiting reagent? 4NH3 + 7O2 --> 4NO + 6H2O

Explanation:

4NH₃      +     7O₂     -->     4NO   +     6H₂O

4 moles       7 moles

58.3 g of NH₃ = 58.3 / 17 = 3.43 moles

126 g of O₂ = 126 / 32 = 3.94 moles

4 moles NH₃ requires 7 moles of O₂

3.43 moles NH₃ requires 6 moles O₂

Available O₂ is only 3 94 moles , so O₂ is in short supply .

Hence O₂ is the limiting reagent .

african americans demonstrated their newly found freedom by relocating often in search of relatives whom they had been separated from during slavery. others established schools to educate freed people and they built institutions such as churches and political organizations to advocate for their rights.
