When gaseous ozone (O3) reacts with liquid water, gaseous hydrogen and gaseous oxygen are formed. What is the balanced equation for this reaction?
ANSWERS OPTIONS
A
O3(g) + H2O(l) → H2(g) + 2 O2(g)
B
2 O3(g) + H2O(l) → H2(g) + 3 O2(g)
C
O3(g) + 2 H2O(l) → 4 H2(g) + 3 O2(g)
D
2 O3(g) + 2 H2O(l) → 3 H2(g) + 2 O2(g)
