TRUE OR FALSE
1. The hydrogen ion and the hydronium ion can be used interchangeably in a chemical equation to represent a hydrogen ion in aqueous solutions.
2. The Bronsted-Lowry model says that an acid is a hydrogen-ion acceptor.
3. The pH scale go from 1 to 15
4. An acidic solution contains more hydrogen ions than hydroxide ions.
5. NaOH is a base
6. Acids and bases are good conductors.
7. Lemon soda has a low pH, therefore is classified as a base.

If you fill your car tire to a pressure of 32 psi (pounds per square inch) on a hot summer day when the temperature is 35°c (95°f), what is the pressure (in psi) on a cold winter day when the temperature is -15°c (5°f)? assume no gas leaks out between measurements and the volume of the tire does not change.
