Answer (Question 1)
A) Na₂O
B) Na and O₂
C) 4Na + 1O₂ → 2Na₂O
D) synthesis reaction
Procedure Question 1
Consider the unbalanced equation
Na + O₂ → Na₂O
A) Remember that the product is the one to the right of the arrow. The product will be Na₂O.
B) Remember that the reactants are the ones placed to the left of the arrow. The reactants in this equation will be Na and O₂.
C) To balance the equation use the trial and error method on both sides of the equation, considering that you need to have the same number of atoms in both sides of the equation. The balanced equation is
4Na + O₂ → 2Na₂O
D) Lastly, given that both reactants combine to form a product this reaction can be classified as a synthesis reaction.
