Answer:
2H2(g) + O2(g) ------------------> 2H2O(g)
Step-by-step explanation:
Basically, the reaction of hydrogen and oxygen is a type of combination reaction and forms steam as its end product. The pure hydrogen burns with a blue flame with oxygen. Industrially, where the combination of hydrogen and oxygen is needed to undergo rapidly, platinum catalyst is introduced. This reaction gives steam rapidly. Platinum speeds up the rate of the reaction of hydrogen and oxygen gases.
