Hope this helped!
Answer: 0.862 L
Explanation:
First off, I'd like to say that I have not done many problems like this, so this could very well be wrong.
So lets do dimensional analysis:
This gives us 10 L / (0.2 * 58) when we cross out units.
Divide and we get 0.862 L
The answer is B.
First write a balanced equation, which is
4Fe + 3O2 => 2Fe2O3.
Then divide the grams of Fe by the molar mass of Fe (16.7/55.85).
You now know the number of moles of Fe, so perform dimensional analysis.
(.299*2*159.70)/(4*1) = 23.9 g
Balance Chemical equation is as follow,
<span> 3 H</span>₂ <span>(g) + N</span>₂ <span>(g) </span>→<span> 2 NH</span>₃ <span>(g)
According to balanced equation, 3 Molecules (3 moles) of Hydrogen reacts with 1 Molecule of N</span>₂ to produce 2 moles (2 Molecules) of NH₃.
Result:
2 Molecules of Ammonia are produced by reacting 3 molecules of Hydrogen and 1 molecule of Nitrogen.
