Question

Oxygen gas and hydrogen gas combine to form water (H2O). Which of these equations correctly represents this reaction?

O + H→HO
2H2+ O2→2H2O
2H2O→O2+ 2H2
H2+ O2→H2O

Answer 1

Answer 2

What do you think? Oxygen and hydrogen are diatomic molecules, and when uncombined, they are always O2 and H2

Answer 3

\[O _{2}+H _{2}\] Would be Hydrogen Paroxide...It would be \[2H _{2}+O _{2}\] This would give you four Hydrogens and two Oxygens, which would give you enough to make \[2H _{2}O\]

Answer 4

@Samara8954 Any thoughts???

Answer 5

Agreed with Ivanna

Answer 6

Well, the first equation is simply wrong because there is no such reaction.
The second equation is correct, because it shows the diatomic molecules as the reactants and the product is water.
The third equation is wrong too because the products and the reactants are switched.
And the fourth equation is correct, but it's unfinished, you need to balance the equation.
