Can someone eplain how to do this ? : identify the limiting reagent and the volume of CO2 formed when 11 L CS2 reacts with 18 L O2 to produce SO2 gas at STP. CS2(g)+3O2(g) → CO2(g)+2SO2(g) A.CS2; 3.3 L CO2 B.O2; 6.0 L CO2 C.CS2; 11 L CO2 D.O2; 27 L CO2

    the limiting reagent dictates how much of the product you can make i.e. the one you have less of. so (1) convert what you have to moles (2) divide each one by it's coefficient e.g. if, aA + bB -> cC; moles of A/a = moles related to coefficient (3) whichever one is lower is the limiting reagent

    to find the volume of CO2 produced using the coefficients determine how many moles you produced based on the limiting reagent (since you can only make that many moles. eg. consider: aA + bB -> cC; if A is the limiting reagent, then moles of C produced: moles of A/a=moles of C/c

    so your saying i would use the final part

    what do you mean by the "final part"?

    CO2(g)+2SO2(g)

    well you have to use all of it. use what the quantities they gave to find the limiting reagent, then use the quantity (about of moles) of the limiting reagent (since you can't make more than what you have, right?) to find how many moles of CO2 you can make based on the coefficients.
