It is not balanced. There should be a 2 in front of H2 and H2O
The chemical reaction between hydrogen and oxygen produces water.
This problem is a Double Reactant. "K+ H20 ----> KOH + H2" would equal "2K + 2H20 ---> 2KOH + H2"
2K + 2H2O --> 2KOH + H2 The balanced equation shows that there is a 2 in front of water.
H2 - hydrogen.
Yep
Zn+ H2O ---> ZnO + H2 Zn+ H2O ---> ZnO + H2
C2h2+ 2h2 = c2h6
Four ammonia plus five oxygen molecules yields 4 nitrous oxide plus six water.
No
It's a chemical reaction.

Yes, it is correct.
