Mon-Day 2
AP Chem - we reviewed the likely and possible exponents/orders for molecules/particles in a rate law (0,1,2, 0.5 , etc.).
Very few of you knew how to do the simple, one-step calculation of determining the initial rate of appearance or disappearance of a product or reactant, respectively, given the initial rate of REACTION in a given experiment! NOTES MUST BE REVIEWED AND SOME REINFORCEMENT PROBLEMS SOLVED EACH DAY - SEE EDLINE AND TEXTBOOK.
We used a given experimental data line to solve for the rate constant at the given temperature, given that we know the rate law exponents already.
We then saw the "formal" way to use a data table and rate law ratios to determine the exponent of each substance in a rate law. When determining the exponent of a given substance, be careful NOT to choose two experiments that have the SAME concentration of that substance.
We then saw how to get the initial rate of reaction for yet another set of initial concentrations of reactants at the SAME TEMPERATURE as conducted in the other experimental trials - the final answer is posted in notes on Edline.

Bio - we tracked the path of two erythrocytes/red blood cells from the point of entry into the right atrium of the heart to the point at which they exit the heart via the aorta.
We then focused on the three possible pathways of circulation: systemic, pulmonary, and even coronary (the heart transports some oxygenated blood to ITSELF).
We looked at the parts of the "fluid", blood, which consists of red blood cells, white blood cells, platelets, and the liquid plasma.# posted by C @ 7:15 AM
