Question

If 50 atoms of carbon reacts with 200 molecules of
oxygen, find out the correct statement(s)
(1) O, is the limiting reagent
(2) 50 molecules of Co, are formed
(3) 100 molecules of Co, are formed
(4) Both (1) & (2)
​

Answer 1

C+O2 → CO

50+ 50 →50

As reaction depends upon C, so C is limiting reagent and O2 is excessive reagent.

So, option (2) is correct only.
