it is the third one: ${\text{2}}{{\text{H}}_{\text{2}}}{\text{ + }}{{\text{O}}_{\text{2}}} \to {\text{2}}{{\text{H}}_{\text{2}}}{\text{O}}$ since we have four atoms of hydrogen at both sides, and we have 2 atoms of oxygen at both sides

Oh.. i was looking at C but i kept thinking it was B. I have one more question though if thats okay

Which statement accurately describes the illustration? Hydrogen has a valence of 1 and oxygen has a valence of 6. Hydrogen has a valence of 1 and oxygen has a valence of 8. Hydrogen has a valence of 1 and oxygen has a valence of 2. Hydrogen has a valence of 2 and oxygen has a valence of 6.

It is the first option, since hydrogen has only one valence electron, whereas oxygen has 6 valence electrons
