H2SO4 + HI → H2S + I2 + H2O
H, 2, SO, 4, + HI → H, 2, S + I, 2, + H, 2, O

H2SO4 + 8HI → H2S + 4I2 + 4H2O
H, 2, SO, 4, + 8HI → H, 2, S + 4I, 2, + 4H, 2, O

H2SO4 + 8HI → H2S + 8I2 + 4H2O
H, 2, SO, 4, + 8HI → H, 2, S + 8I, 2, + 4H, 2, O

2H2SO4 + 2HI → 2H2S + I2 + 4H2O

Answer 1

2H, 2, SO, 4, + 2HI → 2H, 2, S + I, 2, + 4H, 2, O
