You remove a new MDI from its box for administration. What action do you perform before administering?

A flask is filled with 4.00 atm of gaseous F2 and 3.00 atm of gaseous N2. When a lit match is thrown into the flask, the gases react and form gaseous NF3. What is the final partial pressure of NF3 in the flask after the reaction?    

An aerosol is best defined as?

A rigid steel cylinder holds a mixture of three gases: 22.4 g of N2, 16.0 g of O2, and 30.8 g of CO2. The total pressure exerted by the mixture is 6.40 atm. Assuming ideal behavior, what is the partial pressure of O2?

CFC propellants are readily available and replaced HFA propellants on the market.

What is the effect on pressure of doubling both the volume and the absolute temperature of an ideal gas?

Predict whether a reaction occurs, and if so, input the sum of the coefficients for the net ionic equation.  If no reaction occurs enter the number 0.    In the field provided you only need to input the sum of the coefficients of the net ionic equation, so enter a whole number, e.g. 0, 1, 2, 3, etc: barium chloride (aq) + lead(II) acetate (aq)

A [m] g sample of water is injected into an evacuated [vol] L flask at [temp]°C. Part of the water vaporizes and creates a pressure of [press] mmHg. What percentage of the water vaporized?Enter a number in percent to 2 decimal places. Do not enter the %.

A patient that is severely short of breath, wearing a nasal cannula, can’t hold their breath, and requires inhaled medication. Which delivery device would you suggest?

What are the spectator ions in the reaction between sodium hydroxide and magnesium nitrate?
