Answer 1

Answer:

2Mg + O₂ → 2MgO

Explanation:

Given reaction is:

Mg + O₂ → MgO

On the right side, we have:

1 Mg, 1 O

On the left side, we have:

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!

Final and balanced reaction is:

2Mg + O₂ → 2MgO

$\rule[225]{225}{2}$

Hope this helped!
