Calculate the volume of a sample of ammonia (NH3) at 0°C and 1.00 atm if the sample occupies a volume of 0.25 L at 27°C and 0.850 atm.

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

When would a bouncy ball have the most potential energy

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
