Gaseous ammonia chemically reacts with oxygen O2 gas to produce nitrogen monoxide gas and water vapor. Calculate the moles of ox
WINSTONCH [101]

Answer : The number of moles of oxygen needed are, 1.5 moles.

Explanation :

The balanced chemical reaction will be:

4NH_3+5O_2\rightarrow 4NO+6H_2O

Now we have to calculate the moles of oxygen.

From the balanced chemical reaction we conclude that,

As, 6 moles of water vapor produces from 5 moles of oxygen

So, 1.80 moles of water vapor produces from \frac{5}{6}\times 1.80=1.5 moles of oxygen

Therefore, the number of moles of oxygen needed are, 1.5 moles.

Mixtures can be separated into their components by taking advantage of differences in the chemical properties of the components.
Sedaia [141]
The method of separating mixtures by means of their differences in the chemical properties of the components is less convenient because these methods requires reactions therefore needs energy, increasing the costs for the process.
