Answer:
if im not mistaken the answer should be the first one
Answer:
2Mg + O₂ → 2MgO
Explanation:
<u>Given reaction is:</u>
Mg + O₂ → MgO
<u>On the right side, we have:</u>
1 Mg, 1 O
<u>On the left side, we have:</u>
1 Mg, 2 O
- Add 2 as a coefficient with Mg on the right side of rxn. (Will make it 2 Mg, 2 O)
- Now, Add 2 as a coefficient with MgO of the left side of rxn. (Will make it 2 Mg, 2 O)
Hence, the reaction is balanced now!
<u>Final and balanced reaction is:</u>
2Mg + O₂ → 2MgO
