Question

Calculate the volume of air required for complete Air contains 20% by volume of oxygen. Assum same conditions of temperature and pressure. (gases mixture contains 50% H2, 40% CH4 all be required for the complete combustion volumes are measured under the same is = 380 cc of additional O2)

Option 1: What is the volume of air required for the complete combustion of a gas mixture containing 50% H2, 40% CH4 and 10% C2H4, if air contains 20% by volume of oxygen, and the volume of additional O2 required is 380 cc?
Option 2: Calculate the volume of air required for the complete combustion of a gas mixture containing 50% H2, 40% CH4 and 10% C2H4, if air contains 20% by volume of oxygen, and the volume of additional O2 required is 380 cm³.
Option 3: What is the volume of air required for the complete combustion of a gas mixture containing 50% H2, 40% CH4 and 10% C2H4, if air contains 20% by volume of oxygen, and the volume of additional O2 required is 380 cc, under the same conditions of temperature and pressure?
Option 4: Calculate the volume of air required for the complete combustion of a gas mixture containing 50% H2, 40% CH4 and 10% C2H4, if air contains 20% by volume of oxygen, and the volume of additional O2 required is 380 cc, assuming the same conditions of temperature and pressure.

Answer 1

Option 3 is correct. To calculate the volume of air needed for complete combustion of a gas mixture (50% H2, 40% CH4, 10% C2H4) with 20% oxygen, and an additional 380 cc of O2, under the same temperature and pressure conditions. This choice ensures consideration of all relevant factors for an accurate calculation. The correct answer is Option 3: What is the volume of air required for the complete combustion of a gas mixture containing 50% H2, 40% CH4 and 10% C2H4, if air contains 20% by volume of oxygen, and the volume of additional O2 required is 380 cc, under the same conditions of temperature and pressure?

Step-by-step explanation:

Let's simplify the problem:

A gas mixture contains 50% H2, 40% CH4, and 10% C2H4.

For complete combustion, we need to find the volume of air required. The air contains 20% oxygen, and an additional 380 cc of oxygen is needed.

Option 3 correctly states: "What is the volume of air required for the complete combustion of a gas mixture... if air contains 20% by volume of oxygen, and the volume of additional O2 required is 380 cc, under the same conditions of temperature and pressure?"

So, correct answer is Option 3: What is the volume of air required for the complete combustion of a gas mixture containing 50% H2, 40% CH4 and 10% C2H4, if air contains 20% by volume of oxygen, and the volume of additional O2 required is 380 cc, under the same conditions of temperature and pressure?
