300
Substance A has a pH of 3. Substance B has a H+ concentration of 0.00001. Are these acids or bases? Which is stronger and why?
Acids. Substance A is stronger because it has a lower pH.
300
Which of the following is NOT an example of where Organic Compounds could be found? A.) Medicine B.) Food C.) Pure Silver D.) Human Body
C - pure silver has no Carbon/Hydrogen

Explain how Ionic Bonding is different from Covalent Bonding.
In Ionic Bonding the electrons are transferred. In Covalent Bonding the electrons are shared.

Phenolphthalein is an indicator that is colorless at any pH below 9, and pink at any pH above 9. Tim puts Phenolphthalein into a substance and it remains colorless. He concludes that the substance is an acid. Explain why Tim's conclusion is not necessarily correct.
It could have a pH between 7-9, which would make it a base while still remaining colorless in Phenolphthalein.

Duke University's sports teams are called the Blue Devils. Name any two of the following schools' sports team names: Virginia, Oregon, Michigan State, Villanova.
Virginia Cavaliers, Oregon Ducks, Michigan State Spartans, Villanova Wildcats
500
Explain why H2O exists, but H3O and H4O do not exist.
Oxygen has 6 valence electrons, so it can fill its orbital by forming single bonds with two Hydrogen atoms. There is not enough room for a third or fourth Hydrogen atom to form a bond with Oxygen.

Write a balanced equation for the decomposition of water. Hint: Both Oxygen and Hydrogen come in pairs (O2 and H2)
2H2O --> 2H2 + O2

Ryesha is performing an experiment to determine which substance is the strongest. She carefully measures 10 mL each of Ammonia, Bleach, and Drain Cleaner. She slowly adds Vinegar to each substance until a color change occurs. It takes 20 mL to neutralize the Ammonia, 50 mL to neutralize the Bleach, and 100 mL to neutralize the Drain Cleaner. Which of these three bases has the lowest pH? Why?
Ammonia. It's the easiest to neutralize, therefore the weakest.
