Answer:
oxygen is the limiting reagent
Explanation:
cs2(ℓ) + 3 o2(g) −→ co2(g) + 2 so2(g)
from the balanced equation
1 mole carbon disulfide requires 3 mole of oxygen
1.25 moles of csâ‚‚ will required 3.75 mole of oxygen
while 0.57 mole of oxygen will require 0.19 mole of csâ‚‚
comparing, oxygen is the limiting reagent since 0.57 mole of oxygen will require just 0.19 mole out of 1.25 mole meaning csâ‚‚ is in excess.
