Question

I need help asap before midnight tonight! thank you!

Carbon monoxide at a pressure of 1090 mmHg reacts completely with O2 at a pressure of 545 mmHg in a sealed vessel to produce CO2. What is the final pressure in the flask?

Answer 1

The final pressure in the flask is 1635 mmHg.

Step-by-step explanation:

To find the final pressure in the flask, we need to add the pressures of carbon monoxide (CO) and oxygen (O2) together. The initial pressure of CO is 1090 mmHg and the initial pressure of O2 is 545 mmHg. Since CO completely reacts with O2, the final pressure is the sum of the initial pressures, which is 1090 mmHg + 545 mmHg = 1635 mmHg. Therefore, the final pressure in the flask is 1635 mmHg.

Answer 2

The final pressure in the flask is 1635 mmhg

Explanation

Final pressure = partial pressure of Co + partial pressure of O2

partial pressure of CO=1090 mm hg

partial pressure of O2= 545 mm hg

final pressure is therefore = 1090 mm hg + 545 mm hg = 1635 mm hg
