Chem Perio Pointers

1. MAKE SURE YOU UNDERSTAND ALL CONCEPTS THAT WERE DISCUSSED
 When is a chemical reaction in a state of equilibrium?
 What factors affect a system in equilibrium? How does each factor affect the direction of the reaction, the amount of reactants and products, and the value of Keq?
 What are the different definitions of acids and bases and how do they differ?
 What acid strength trends are followed by binary acids? Oxo/oxyacids?
 Why do aqueous solution of salts exhibit acidic, basic, or neutral properties?

2. MAKE SURE YOU KNOW HOW TO…
 Write Keq expression (Kc and Kp) for homogenous and heterogeneous reaction
 Relate Kc and Kp
 Solve Keq problems
 Determine the direction of a system approaching equilibrium (Q vs. Keq)
 Solve for new Keq when a given reaction is manipulated
 Solve for hydronium and hydroxide concentrations, pH and pOH of strong and weak acids and bases.
 Solve for % ionization/dissociation

Contact Print Forms and Payments

Deadline for grad pic contact print order forms and payments is during Homeroom time, Monday, October 12. Place the forms and payments in the envelope and return to your class presidents. The prints are yours to keep.

Class presidents and secretaries, you are supposed to list down the orders of your classmates so that you have your own copy and you can check once the prints are delivered.

Submit orders and payments to Ma'am Butaran as soon as collection and listing is done.

For those who have clarifications regarding the order forms, you may ask your class presidents or any batch council officer.
