Answer:
HI + LiHSO3 → H2O + SO2 + LiI
Step-by-step explanation:
Step 1: Data given
hydroiodic acid = HI
lithium hydrosulfite = LiHSO3
Step 2: The unbalanced equation
HI + LiHSO3 → H2O + SO2 + LiI
Step 3: the balanced equation
On the left side we have 2x H (1x in HI and 1x in LiHSO3). On the right side we have 2 moles H (in H2O). The amount of H is balanced.
The amount of moles I , on the left is 1, The amount of moles I on the right is 1 mol. This amount is balanced.
On the left side we have 3x O. (3x in LiHSO3). On the right side we have 3x O, (1x in H2O and 2x in SO2). The amount of O is balanced.
HI + LiHSO3 → H2O + SO2 + LiI
