Hydrogen (H2) and oxygen (O2) combine to make water (H2O) in the following equation.

6H2 + 3O2 -> ?H2O
How many water molecules would be produced?
A. Six
B. Four
C. Three
D. Five

9 answers

1. Six
2. 12 oxygen atoms
3. Reactant bonds break and atoms rearrange to form new product combinations
4. Two
5. No, it does not because the number and mass of atoms are conserved even though the number of molecules is not
1. The equation as written is not correct. The proper way to write the equation is
2H2 + O2 ==> 2H2O
2. The question you've asked can't be answered BECAUSE you don't say how much hydrogen and how much oxygen are used.
3. However, I think I know what you mean so the balanced equation you have written would be 6H2 + 3O2 ==> 6H2O and I would choose A for the answer.
