A mixture of gases has a total pressure of 12.75 atm. The mixture contains neon, argon and helium. The partial pressure of the neon is 5.80 atm. The partial pressure of the
argon is 2.50 atm. What is the partial pressure of the helium?

Use the periodic table to determine the electron configuration of dysprosium (dy) and americium (am) in noble-gas notation.

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.
