Introduction to Python ?

A 5.00L tank at 28.4°C is filled with 6.03g of sulfur hexafluoride gas and 8.62g of chlorine pentafluoride gas. You can assume both gases behave as ideal gases under these conditions.

Calculate the partial pressure of each gas, and the total pressure in the tank. Round each of your answers to 3 significant digits.

1) sulfur hexafluoride: partial gas = ?

2) chlorine pentafluoride: partial gas = ? 

3) total pressure in tank = ?

For many purposes we can treat nitrogen N2 as an ideal gas at temperatures above its boiling point of −196.°C.

Suppose the temperature of a sample of nitrogen gas is lowered from 17.0°C⁢ to −21.0°C, and at the same time the pressure is changed. If the initial pressure was 5.1 atm and the volume increased by 35.0%, what is the final pressure?

Round your answer to 2 significant digits.

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.

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.

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 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.

Paraphrase this equation

Part A: The expression that represents the amount of money the store made is (24)(35) + (15)(15) - 120.

Part B: To calculate the amount of money the store made, we need to find the total revenue from selling the keyboards and phone chargers and then subtract the cost of purchasing them. The revenue from selling 24 keyboards at $35 each is (24)(35) = $840, and the revenue from selling 15 phone chargers at $15 each is (15)(15) = $225. So the total revenue is $840 + $225 = $1065. Since the store bought the items for $120, we subtract that from the revenue to get the profit: $1065 - $120 = $945.

Part C: (24)(35) + (15)(15) - 120 = 840 + 225 - 120 = $945. Therefore, the value of the expression is $945, which represents the profit the store made from selling the keyboards and phone chargers.

If 15 is added to a number then it is increased by 20%. Find the Original number?

a. 55

b.65

c.75

d.90
