True or false: Acids are more dangerous than bases. Explain.

Suppose that a 100 mL sample of ideal gas is held in a piston-cylinder apparatus. Its volume could be increased to 200 mL by: a. increasing the temperature from 25oC to 50oC at constant pressure. b. increasing the pressure from 1.00 atm to 2.

A vessel of volume 22.4 dm3 contains 2.0 mol h2 and 1.0 mol n2 at 273.15 k initially. all the h2 reacted with sufficient n2 to form nh3. calculate the partial pressures and the total pressure of the final mixture.

Consider equimolar samples of different ideal gases at the same volume and temperature. gas a has a higher molar mass than gas b
