Question

Volume of O2=358 What volume of H2O(g) is produced by the reaction under the same conditions?

Answer 1

The question is kind of unclear, so I am assuming the following :

1) H₂O is produced by the reaction of the given oxygen with hydrogen

2) By 358, I am assuming that it is 358 ml

3)By "Under the same conditions", I am assuming that the volume of hydrogen supplied is equal to the volume of oxygen = 358 ml

Now, we proceed with the solution:
As per the reaction:

2H₂ + O₂ ----> 2H₂O,

We see that 2 volumes of hydrogen react with 1 volume of oxygen to give 2 volumes of water.

We can see that as oxygen is present in excess, the reaction is controlled by the amount of hydrogen present.

Hence, 358 ml of H₂ reacts with 179 ml of Oxygen to produce 358 ml of H₂O.

Hence, products = 358 ml H₂O and 179 ml O₂
