Hydrogen gas reacts rapidly with oxygen gas in the presence of a platinum catalyst. which equation correctly represents this
reaction?
h2(g) + o2(g) + pt → h2(g) + o2(g)
h2(g) + o2(g) → h2(g) + o2(g) + pt
2h2(g) + o2(g) _pl_2h2o(g) + pt
2h2(g) + o2(g)_p4, 2h, o(g)

2H2(g) + O2(g) -pt---> 2H2O

2H2(g) + O2(g) > 2H2O(g)

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.

explanation:

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
