The first ionization energy, E E , of a potassium atom is 4.19 × 10 2 kJ / mol 4.19×102 kJ/mol . What is the wavelength of light, in nanometers, that is just sufficient to ionize a potassium atom? Refer to the values for constants.

The pressure in a fluid is affected by which characteristics of that fluid

Water (2510 g ) is heated until it just begins to boil. if the water absorbs 5.09×105 j of heat in the process, what was the initial temperature of the water?

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
