Question

In a reaction \[\ce{x + y + z2 -> xyz2}\] identify the Limiting reagent if any, in the following reaction mixture.

50 atoms of x + 25 atoms of y + 50 molecules of z₂

Answer 1

Reaction: \[\ce{x + y + z2 -> xyz2}\]

50 atoms of x + 25 atoms of y + 50 molecules of z₂
25 atoms of y react with 25 atoms of x and 25 molecules of z₂.

So y is the limiting reagent.
