Question

question 1 (2 points)
when balanced, what is the stoichiometric coefficient on li₂so₃?
h₂so₃ + lioh → h₂o + li₂so₃
none of these
two
four
three
understood one

Explanation:

Step1: Balance Li atoms

There are 2 Li atoms in $Li_2SO_3$. So we need 2 moles of LiOH on the left - hand side: $H_2SO_3+2LiOH
ightarrow H_2O + Li_2SO_3$.

Step2: Balance H and O atoms

On the left - hand side, we have $H_2SO_3$ with 2 H atoms and 2 LiOH with 2 H atoms, a total of 4 H atoms. On the right - hand side, in $H_2O$, to balance the H atoms, we need 2 moles of $H_2O$. The balanced equation is $H_2SO_3 + 2LiOH=2H_2O+Li_2SO_3$.
