Respuesta :
The subscript is 2, while the coefficient, since it has non, it would be a one.
Answer: one
Answer: one
When the equation is correctly balanced , the coefficient of O₂ = 3.
What is Balancing of Equation ?
The amounts of reactants and products required to satisfy the Law of Conservation of Mass are given in a balanced chemical equation.
This indicates that on the reactant side of the equation, there are the same number atom as there are on the product side of the equation.
In the question the given equation is
C₂H₄+O₂→CO₂+H₂O
When the equation is correctly balanced using smallest whole numbers
C₂H₄+3O₂→2CO₂+2H₂O
To determine if the equation is balanced or not , if we will check the reactant molecules with the product molecules.
C = 2 in reactant and product
O=6 in reactant and product
H=4 in reactant and product
So the equation is balanced
and so the coefficient of O₂ = 3
