Answer:
2Mg + O2 → 2MgO
Explanation:
Answer:
2Mg + O2 → 2MgO
Explanation:
Step 1: Data given
Magnesium = Mg
Oxygen = O2
magnesiumoxide = MgO
Step 2: The unbalanced equation
Mg + O2 → MgO
Step 3: Balancing the equation
On the left we have 2x O so on there right, we should mulitply MgO by 2 so we have on each side 2x O
Mg + O2 → 2MgO
On hte right side we have 2x Mg, so we have to multiply on the left side Mg by 2 to have the same amount of Mg on both sides
2Mg + O2 → 2MgO
Now the equation is balanced
