Explanation:
Please kindly check attachment for the detailed step by step solution of the given problem.
We need to multiply the 2nd equation by two and reverse it.
Option D
<h3><u>Explanation:</u></h3>
In the 2nd reaction, it says H₂ +F₂ =2HF.
So, multiplying it by 2 gives 2H₂ + 2F₂ = 4HF.
Reversing it gives 4HF = 2H₂ +2F₂.
Now the 1st equation says 2H₂ +O2 =2H₂O.
Adding them gives
2H₂ +O₂ +4HF = 2H₂ +2F₂ +2H₂O.
Or, O₂ +4HF = 2H₂O + 2F₂.
this is the balanced reaction.
