Question

hydrogen and oxygene react to form water l. How many molecules of O2 are required to produce 0.6 of H20​

Answer 1

Answer:

It is required 0.3 molecules of O2 to produce 0.6 molecules of H2O

Explanation:

The water´s formation reaction is: 2H2 + O2 --> 2H2O

This reaction shows the molecular O2:H2O ratio: 1:2.

Then, if we want to know how many molecules of O2 are required to produce 0.6 of H20​, it is necessary calculate as it showed next:

0.6 molecules H2O * (1 molecula O2 / 2 molecules H2O)= 0.3 molecule O2
