Answer:
The volume of ammonia produced by 4.2 L of hydrogen and excess nitrogen is 2.8 L.
Explanation:
Given data:
Volume of H₂ = 4.2 L
Volume of NH₃ produced = ?
Solution:
First of all we will write the balance chemical equation:
N₂ + 3H₂ → 2NH₃
Hydrogen is limiting reactant and volume ratio is,
H₂ : NH₃
3 : 2
4.2 : 2/3 × 4.2 = 2.8 L
The volume of ammonia produced by 4.2 L of hydrogen and excess nitrogen is 2.8 L.
Answer:
C. Theories have been confirmed through tests; hypotheses haven't.
Hope this helps!!
Explanation:
Concentration ;
The reaction see a change in pressure per second. By the ideal gas law, this quantity would correspond to a change in concentration, of
where the ideal gas constant .
By definition,
Therefore, for this particular reaction
