Answer:
Only the oxygen needs to be balanced. There are equal numbers of hydrogen and carbon
Explanation:
Given expression:
C₂H₄ + O₂ → 2H₂O + 2CO₂
The law of conservation of mass suggests that chemical equations be balanced since atoms are neither created nor destroyed in the course of a chemical reaction. In retrospect, bonds are broken and chemical species are change to another form.
From the given equation, only oxygen is not balanced. This flouts the law of conservation.
On the reactant side, we have 2 oxygen on the product, we have 6.
