I can’t see the picture for some reason but if I were to guess, I would say Pangea.
First question. Applying ideal gas equation PV=nRT, P= 101.3 x 10³Pa = 1atm. therefore, 1 x 260 x 10^-3 = n x 0.082 x 294.( Temperature in kelvin=273+21). n = 0.01 moles. Volume of gas at STP= n x 22.4 = 0.01x22.4 = 0.224L. Hope this helps
I believe the answer would be true
88 Grams because the principal of conservation of mass states total mass in equals total out so 200 in 122+88=200 out
