Tues-Day 2
Bio - we explained how vaccines work by stimulating a primary immune response by using a weakened/attenuated form of the pathogen or part of the pathogen that contains its unique antigens.
We showed the benefits of vaccines in preparing your immune system against a future invasion by the same pathogen, even in its normal/non-weakened form because of the already circulating antibodies and memory B and T cells. This way, you will have a rapid immune response against this pathogen and very likely avoid infection or sickness.
AP Chemistry - we showed how to write an equilibrium constant expression from the balanced equation of a given reaction noting that ONLY gases and aqueous substances go into the expression.
We then discussed the meaning of the K values with respect to reactant and product concentrations AT EQUILIBRIUM.
We then discussed, Q, the reaction quotient , which is IDENTICAL in form but contains the INITIAL (NOT THE EQUILIBRIUM) concentrations of the reactants and products.
We then compared Q to K to determine the direction that the reaction "shifts to" as equilibrium is reached.
