Three 3.0 L sealed flasks in the same room, each at a pressure of 788mmHg contain Ne, Ar, and Kr respectively. a) which of the flasks contain the greatest number of moles of gas?

b) which of the flasks contain the greatest mass of gas?

c) If Ar flask was heated and Kr flask was cooled, which of the three flasks would be at the highest pressure?

d) If the temperature of the Ne was lowered while the Kr was raised, which of the three gases would have the greatest kinetic energy?

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.
