Question

1) a) If a sample of pure hydrogen gas is ignited very carefully, the hydrogen burns gently, combining with the oxygen gas of the air to form water vapor. Write the unbalanced chemical equation for this reaction. (Include states-of-matter under the given conditions in your answer.)

Answer 1

H₂ (g) + O₂ (g) ⇒ H₂O (g)

Step-by-step explanation:

Hydrogen and oxygen gas both exist as diatomic molecules. The water is in gaseous state due to the heat given off by the combustion reaction.
