Question

question 2 (2 points)
when one mole of each reactant is mixed, which reactant is the limiting reagent?
h₂so₃ + lioh → h₂o + li₂so₃
○li₂so₃
○h₂so₃
○h₂o
○there is no limiting reactant
○lioh

Explanation:

Step1: Balance the chemical equation

$H_2SO_3 + 2LiOH
ightarrow 2H_2O+Li_2SO_3$

Step2: Analyze mole - ratio

From the balanced equation, the mole - ratio of $H_2SO_3$ to $LiOH$ is $1:2$. Given 1 mole of each reactant, for 1 mole of $H_2SO_3$, 2 moles of $LiOH$ are required. But we only have 1 mole of $LiOH$.

Answer:

E. LiOH
