Question

Consider the balanced equation below.

2H2S + 3O2 Right arrow. 2SO2 + 2H2O

Which option gives the correct mole ratios?
H2S:SO2 = 2:2 and O2:H2O = 3:2
H2S:SO2 = 2:3 and O2:H2O = 3:2
H2S:SO2 = 4:4 and O2:H2O = 5:4
H2S:SO2 = 4:6 and O2:H2O = 4:4

Answer 1

Answer:

4:6    and  4:4

Explanation:

double the right side so double the left side to get these ratios
