Three of the primary components of air are carbon dioxide, nitrogen, and oxygen. In a sample containin a mixture of only these gases at exactly 1 atm, the partial pressures of carbon dioxide and nitrogen are given as
PCO2=0.285
torr and
PN2=593.525
torr. What is the partial pressure of oxygen?

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
