A volume of 485 mL of argon at 45.0°C and 1.00 atm is combined with 210. mL of xenon at 23.7°C and 3.91 atm in a new flask that has a volume of 350. mL. What is the total pressure (in atm) of gas in the flask at 36.0°C?
The wavelengths of the sodium doublet can be accurately measured despite the fact that they are very short. The IUPAC standard for the meter is, in fact, based on the wavelength of a particular line in the emission spectrum of the element krypton

how many calories of heat must be added to raise the temperature of 40 g of water fro 25 Celsius to 50 Celsius
What is its solubility under atmospheric conditions? (The partial pressure of CO2 in air is 0.00055 atm.) Assume that CO2 obeys Henry's law.
NH3 can react with BF3, forming NH3¾BF3. In this reaction, 1) NH3 acts as a Brønsted base, accepting a proton from the BF3 molecule. 2) NH3 acts as a Lewis base, donating a proton to the BF3 molecule
