Answer: The coefficient for [tex]O_2(g)[/tex] is 12.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
[tex]C_{10}H_{12}O_4S(s)+12O_2(g)\rightarrow 10CO_2(g)+SO_2(g)+6H_2O[/tex]
Thus in the reactants, there are 12 molecules of oxygen in balanced chemical equation. Thus the coefficient for [tex]O_2(g)[/tex] is 12.
The coefficient of O₂ when the equation is balanced and all the coefficients
are reduced to their lowest whole number term is 12.
The chemical equation is represented as follows:
C₁₀H₁₂O₄S(s) + O₂(g) → CO₂(g) + SO₂(g) + H₂O(g)
Now let's balance the equation and make sure the number of moles of
element in the reactant and product side are the same.
Therefore, the balance chemical equation will be as follows:
C₁₀H₁₂O₄S(s) +12 O₂(g) → 10CO₂(g) + SO₂(g) + 6H₂O(g)
From the balanced equation we can see that oxygen molecule has a
coefficient of 12 on the reactant side.
The number of moles of oxygen on both sides of the equation is 28.
