A model of (CH20)4 was created using colored beads. Carbon atoms were represented by black
beads, hydrogen atoms by red beads, and oxygen
atoms by blue beads. Which of the following
combinations of beads shows an accurate model of
(CH20)4?

Agas mixture with a total pressure of 745 mmhg contains each of the following gases at the indicated partial pressures: co2, 245 mmhg ; ar, 119 mmhg ; and o2, 163 mmhg . the mixture also contains helium gas. part a what is the partial pressure of the helium gas? phe p h e = nothing mmhg request answer part b what mass of helium gas is present in a 10.2-l sample of this mixture at 283 k ? m m = nothing g request answer
