The only one i can make sense out of would be:

(1) "</span><span>After the reaction was completed, the student failed to withdraw the rod to its original position before taking the second buret reading." </span><em>this would affect the volume, since the rod is submerged in the solution, it would affect the reading (it would appear as a greater volume).</em>
Hey there!
5 moles will be produced.
N₂ has a molar mass of 28.014 g/mol.
Convert 70g to mol:
70 ÷ 28.014 = 2.5
In N₂ there are 2 nitrogen atoms. In NH₃ there is 1 nitrogen atom.
So, there will be twice as many moles of NH₃ because every one molecule of N₂ will produce two molecules of NH₃.
2.5 x 2 = 5 moles
Hope this helps!
