Answer 2

Answer:

Both carbon monoxide and hydrogen are a colorless, odorless gas. Both are flammable over a wide range of vapor/air mixtures. The vapors will be lighter than air. The mixture is potentially toxic especially if the mixture is high in carbon monoxide. Under prolonged exposure to fire or intense heat the container may violently rupture and rocket.
