Question

If 10 volumes of dihydrogen gas react
with 5 volumes of dioxygen gas,
how
many volumes of water vapour would be
produced?​

Answer 1

Answer:

Explanation:

Dihydrogen gas reacts with Dioxygen gas

2H2+O2 gives 2H2O

Here, 2 volumes of dihydrogen gas react with 1 volume of dioxygen to produce 2 volumes of water vapour.

So, if 10 volumes of dihydrogen gas react with 5 volume of dioxygen then it will produce (2\times5 = 10  volumes of water vapour.

Answer 2

Explanation:

Thus, 10 volumes of dihydrogen react with 5 volume of oxygen to form 10 volumes of water.
