User: How many liters of chlorine gas can be produced when 0.98 L of HCl react with excess O at STP?

4HCl(g) + O(g) 2Cl(g) + 2HO(g)

A0.98 L
C3.9 L
B0.49 L
D2.0 L

Verified Answer :

The reactant being used up is called limiting reagent as it limits the total amount of product produced.

if 4 units of HCL gives 2 units of Cl therefore
4:2
0.98:x
x=(0.98*2) /4
x=0.49L
