Question

What volume of O2 is required to react with C S2(1) to
produce 4.0L of CO2(g)?

Answer 1

12 L of O₂.

Step-by-step explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

CS₂ + 3O₂ —> CO₂ + 2SO₂

From the balanced equation above,

3 L of O₂ reacted to produce 1 L CO₂.

Finally, we shall determine the volume of O₂ needed to produce 4 L of CO₂. This can be obtained as follow:

From the balanced equation above,

3 L of O₂ reacted to produce 1 L CO₂.

Therefore, xL of O₂ will react to produce 1 L CO₂ i.e

xL of O₂ = 3 × 4

xL of O₂ = 12 L

Thus, 12 L of O₂ is needed for the reaction.
