Explanation:
Unbalanced chemical reaction
Mg + O₂ ⇒ MgO
Reactants Elements Products
1 Magnesium 1
2 Oxygen 1
Balanced chemical reaction
2Mg + O₂ ⇒ 2MgO
Reactants Elements Products
2 Magnesium 2
2 Oxygen 2
Conclusion
The coefficients of the balanced equation are 2, 1, 2
Answer:
The coefficient for oxygen, in this equation is 1
Explanation:
Step 1: The unbalanced equation
2Mg + O2 → MgO
Step 2: Balancing the equation
2Mg + O2 → MgO
On the left side we have 2x Mg, on the right side we have 1x Mg(in MgO).
To balance the amount of Mg we have to multiply MgO by 2.
Now the amount of O is on both sides also equal.
The equation is balanced.
2Mg + O2 → 2MgO
The coefficient for oxygen, in this equation is 1
