Ahh there isn’t a group 29 on the periodic table, but do you mean which element had the atomic number 29 because that would be Copper (Cu).
Hope this helps :)

Answer :
In my opinion , answer is A
Answer:
295.96 K ( = 22.81 degrees C)
Explanation:
PV = n RT R = .082057 L-Atm / (K-Mol) n = 3.5 P = 1 atm V = 85 liters
(1)(85) = 3.5 (.082057)(T)
solve for T = 295.96 K
It is the atomic number. So it is D.
