The name of that is Copper.
Valence election configuration is the electrons in the shell that equal to 8. it what forms chemcial bonds. Electron configuration is distribution of elections of an atom.
Hydroxy derivatives of aliphatic hydrocarbons are called as alcohols.
PV = nRT —> n = PV/RT
P = 2.90 atm
V = 4.80 L
R = 0.08206 L atm / mol K
T = 62.0 + 273 = 335 K (make sure you convert from celsius to kelvin)
n = (2.90 • 4.80) / (0.08206 • 335) = 0.506 moles of gas
