Amore experienced colleague mentions to you that you should aim for a dissolved oxygen concentration around 1.0 mg/l at day 5 of the experiment. they show you data from a similar wastewater spill that happened last year, in which the bod5 of the stream water was 60 mg/l. from your previous experiment, you found that the dissolved oxygen concentration at day 0 was 10 mg/l. based on this information, what dilution factor, p, should you try in your reactor?

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.
