What is the correct sequence of coefficients when this equation is balanced? ___cs2(l) + ___o2(g) → ___co2(g) + ___so2(g)?
iris [78.8K]

Answer: the sequence is 1, 3, 1, 2.


Explanation:


1) Given equation: CS₂(l) + O₂(g) → CO₂(g) + SO₂(g)


2) To balance:


i) initially C is balanced: 1 atom in the left side, and 1 atom in the right sides


ii) Add coefficient 2 in front of SO₂ to have 2 atoms in each side.


That leads to: CS₂(l) + O₂(g) → CO₂(g) + 2SO₂(g)


iii) Count the O atoms; there are 2 atoms in the left, and 6 atoms in the right side. So, add a coefficient 3 in front of O₂ (in the left) and you get:


CS₂(l) + 3O₂(g) → CO₂(g) + 2SO₂(g)


4) You can verigy that now the equation is balanced:


C: 1 in the left, and 1 in the right


S: 2 in the left, and 2 in the right


O: 6 in the left, and 6 in the right.


5) So, the sequence is 1, 3, 1, 2.


Remember, when the none coefficient is shown it is because it is 1.
