Oxidation Portfolio Reflect Review your completed activities that are to be submitted to your learning
coach and consider the following:
1. What were the strengths of your investigation? What were the limitations?
How could you address the limitations?
2. What did you learn from your investigation?
3. How could the results of investigations like the one you did be used?
4. What questions do you still have about your investigation?

How many moles are in 43.9 l 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.

Calculate the ph at the equivalence point for the titration of a solution containing 150.0 mg of ethylamine (c2h5nh2) with 0.1000 m hcl solution. the volume of the solution at the equivalence point is 250.0 ml. kb forethylamine is 4.7 × 10−4 .
