Given the balanced equation representing a reaction:
4nh3 + 5o2 ==> 4no + 6h2o
what is the minimum number of moles of o2 that are needed to completely react with 16 moles of nh3?
(1) 16 mol (3) 64 mol
(2) 20. mol (4) 80. mol

4 NH₃ + 5 O₂ = 4 NO + 6 H₂O

4 moles NH₃ 5 moles O₂
16 moles NH₃ ? moles O₂

moles O₂ =  16 * 5 / 4

moles O₂ = 80 / 4

= 20 moles of O₂

Answer (2)

hope this helps!

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
