5 True/False Questions

1. surface area → amount if area exposed; the more there is the higher the reaction rate and lower the reaction time

   True        False

2. liter → Si unit that measures distance

   True        False

3. science → an atom that has a net positive or negative electric charge (protons and electrons aren't the same)

   True        False

4. nonmetal → right side, bullies, brittel when solids, don't conduct heat, often dull, often gases or liquids, diatomic, make negative ions, conalent bonds

   True        False

5. melting point= freezing point → solid to a liquid or liquid to a solid
