Answer:

so 0.15 moles X 22.4 dm3/mole=3.36 dm3. Next we find the moles of hexane combusted, and then the moles of CO2. Finally, we find the volume of CO2 using the fact that at STP, 1 mole of gas = 22.4 dm3.

I want to produce 100 moles of N2. Now how many moles of NO do I need to start with?
cluponka [151]

Answer:

120 moles of NO

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

4NH₃ + 6NO —> 5N₂ + 6H₂O

From the balanced equation above,

6 moles of NO reacted to produce 5 moles of N₂.

Finally, we shall determine the number of mole NO needed to produce 100 moles of N₂. This can be obtained as follow:

From the balanced equation above,

6 moles of NO reacted to produce 5 moles of N₂.

Therefore, Xmol of NO will react to produce 100 moles of N₂ i.e

Xmol of NO = (6 × 100)/5

Xmol of NO = 120 moles

Therefore, 120 moles of NO is needed for the reaction.
