Answer:
A 2.8 liters
Explanation:
Step 1: Write the balanced equation
N₂ + 3 H₂ ⇄ 2 NH₃
Step 2: Establish the appropriate volume ratio
At the same temperature and pressure, the volume ratio of H₂ to NH₃ is 3:2.
Step 3: Calculate the volume of ammonia produced from 4.2 L of hydrogen
4.2 L H₂ × 2 L NH₃/3 L H₂ = 2.8 L
I can help you but what is the question here?
Melting cheese is a physical change.
Answer: The element is sulfur and the atomic mass is 32.07
Explanation: wasn’t sure what you were asking so gave you both
<h2>The chemical reaction occurs when one element replaces another compound.</h2>
Explanation:
Chemical reaction : It is the reaction in which two or more substances react to form some new substance .
Like : Burning of fuel etc
We have different types of reactions occurring around us like:
- Combination reaction
- Decomposition reaction
- Displacement reaction
- Double decomposition reaction
- Redox reaction
Displacement reaction
it is a reaction between element and a compound in which more reactive element displaces less reactive from its compound
i.E CuSO₄ + Zn --> ZnSO₄ + Cu
(copper sulphate ) (Zinc sulphate )
In this we follow reactivity series and accordingly we come to know whether the reaction will occur or not .
Like if the above asked reaction is modified as this :
ZnSO₄ + Cu ------> No reaction
This is because copper being less reactive than Zn cant displace zinc .Hence , no reaction occur .
