PT1. Oxygen and sulfur have similar chemical properties due tohaving six valence electrons.  Both form molecules withtwo hydrogen atoms.  Surprisingly, water (H2O)is a liquid, yet H2S is a gas, even though sulfur ismuch larger and heavier than oxygen.  Why? Explainfully.

- Why is a solution at pH 7.0 said to be neutral?
- What is the H+ concentration and pH of a 1mMsolution of NaOH?
- If the pH of a solution is 5.0, what is the concentration ofOH- ions?
