1. A buffered solution consists of a weak acid (HA) and its conjugate base (A-). Suppose a strong base is added to the solution. Which statement below is TRUE? * A. The concentration of the weak acid increases.

B. The strong base reacts with the weak acid.

C. The strong base reacts with the conjugate base.

D. The Ka of the acid decreases.

2. A buffered solution consists of a weak base (B) and its conjugate acid (BH+). Suppose a strong acid is added to the solution. Which statement below is TRUE? *

A. The concentration of the weak base increases.

B. The strong acid reacts with the conjugate acid.

C. The concentration of the conjugate acid increases.

D. The Kb of the base decreases.

the mass of the cathode increases because ions from the solution get reduced to atoms and become part of the cathode.

the answer is c

tell me if wrong

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.  

it would only be the stuff in module eight so you need to study all the lessons in that you also could check the flvs

hope this : )
