Question

In a reaction in which hydrogen reacts with oxygen to produce water , which substance/s is/are reactants?

Answer 1

Answer:

When molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide. These two processes are represented by the two chemical equations shown at right.

Answer 2

Answer:

The reactants are hydrogen(H₂) and oxygen(O₂).

Explanation:

The reactants are the substances that on reacting with each other will give rise to desired species.

The reaction will proceed as follows,

$2H_2+O_2\rightarrow 2H_2O$       (1)

Where,

H₂=hydrogen gas

O₂=oxygen gas

H₂O=water

In equation (1) we can see that hydrogen(H₂) and oxygen(O₂) give rise to water(H₂O).

Hence, the reactants are hydrogen(H₂) and oxygen(O₂).
