A 9.00L tank at 13.6°C is filled with 11.8g of dinitrogen monoxide gas and 2.27g of chlorine pentafluoride gas. You can assume both gases behave as ideal gases under these conditions.

Calculate the mole fraction of each gas. Round each of your answers to 3 significant digits.

1) Gas: Dinitrogen monoxide 

Mole Fraction: ?

2) Gas: Chlorine pentafluoride

Mole Fraction: ? 

A gas storage cylinder in an ordinary chemical laboratory measures 3.5cm wide and 14.cm high. This is the label on it.

Contents: N2 gas 

Pressure: 9.92 atm 

If the cylinder is opened and the gas allowed to escape into a large empty plastic bag, what will be the final volume of nitrogen gas, including what's collected in the plastic bag and what's left over in the cylinder? Write your answer in liters.

Round your answer to 2 significant digits.

A chemistry graduate student is designing a pressure vessel for an experiment. The vessel will contain gases at pressures up to 350.0MPa. The student's design calls for an observation port on the side of the vessel (see diagram below). The bolts that hold the cover of this port onto the vessel can safely withstand a force of 5.00MN.

Calculate the maximum safe diameter w of the port. Round your answer to the nearest 0.1cm.

A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stainless-steel cylinder that measures 40.0cm wide and 48.0cm high. The maximum safe pressure inside the vessel has been measured to be 5.10MPa.

For a certain reaction the vessel may contain up to 2.73kg of dinitrogen difluoride gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. Write your answer in degrees Celsius.

Round your answer to 3 significant digits.

1. suppose a particular consumer has 8 birr to be spent on two goods x and y. thr unit price good x=5 bir and unit price y of  3 birr

Sometimes in lab we collect the gas formed by a chemical reaction over water. This makes it easy to isolate and measure the amount of gas produced.

Suppose the CO gas evolved by a certain chemical reaction taking place at 50.0°C is collected over water, using an apparatus something like that in the sketch, and the final volume of gas in the collection tube is measured to be 64.5mL.

Calculate the mass of CO that is in the collection tube. Round your answer to 2 significant digits. You can make any normal and reasonable assumption about the reaction conditions and the nature of the gases.

Pathophysiology Case Scenario:

Triage Your Patients!

You are a clinic triage nurse responsible for medically prioritizing patients. Four patients present at the same time. Explain which patient should be treated first and which should be treated last. Support your reasons with information from the text or credible outside sources.

1. Infant with fever, audible inspiratory stridor, and restlessness.

2. Young male in his mid-20s with nasal drainage and hoarseness.

3. Middle-aged woman with fever, severe body aches, and nasal congestion.

4. Man in his late 50s with stage III carcinoma of the bronchioles complaining of nausea and significant pain.
