Ideal gas equation was used to explain the theory.


why gases such as oxygen used at hospitals are compressed. Why must compressed gases be shielded...
Use the kinetic molecular theory to explain why: -Gases can be compressed much more than liquids or solids. -A blood sample to be analyzed for ammonia gas must be cooled immediately after the blood is drawn from the patient.
A portable oxygen tank (similar to one used in hospitals) measures 30-cm-diameter and 1.3-m-high. The tank is pressurized to 13,800,000 Pa (gauge). A 12.5-mm-diameter valve is located at the top and when fully-opened, oxygen exits at a velocity of 1.5 m/s (25oC). Assuming a constant exit velocity, determine the pressure (in MPa gauge) after two minutes. Assume isothermal conditions.
Topic: Practice exercise on gas laws. You must write the equation you are using to solve the exercise. 2. An unknown gas occupies an initial volume of 0.256 L when its temperature equals 121ºC. What will be the final volume if the temperature drops to 25ºC? 3. A sample of a gas has an initial pressure equal to 744 mmHg when its initial temperature is 22ºC. What is the final temperature in degrees Celsius if the pressure increases to 766...
Why must X-rays be used in crystal structure determinations rather than visible light? Why must the light used in crystal structure determinations be monochromatic? That is, what would happen to a peak in an XRD pattern if polychromatic rather than monochromatic light were used?
Glucose is burned with 80.0% excess air. The degree of completion is 1.00. the outlet gases from burner are passed through a separator that removes 66.6 % of the water from the gases. The gas stream that exits the separator, which has less water in it, leaves at 1.6 bar and 82 degrees centigrade -Draw a community sanctioned diagram of this process. -To what pressure must this gas be compressed at constant temperature before water starts to condense. -To what...
Topic: Practice exercise on gas laws. You must write the equation you are using to solve the exercise. 1. A sample of Argon gas occupies an initial volume of 5.40 L when its pressure is 6.52 atm. What will be the final pressure of the gas if its volume increases to 9.73 L? 2. An unknown gas occupies an initial volume of 0.256 L when its temperature equals 121ºC. What will be the final volume if the temperature drops to...

Hospitals are finding the importance of developing strategies to become a high reliability organization (HRO). Why would this be important in healthcare and share at least 1 strategy that should be used to develop this type of an organization?
If 241 mL of oxygen gas is compressed from 18.6 atm to 36.5 atm of pressure, what is the new volume (in mL) at constant temperature?
