The study of what we can know and how we know it.
Whats the saying of Law of Conservation and Mass.
Matter can never be created or destroyed it can only can change form and be rearanged.
properties of Bases

excess of OH- ions
slippery feel
dangerous for skin
turns red litmus paper blue

List 4 characteristics of Ionic Bonds
1. Transfer of Electrons
2. Formed between Metals and Non-Metals
3. They form Ions
4. Ions of the opposite attract
Definition of Lurking Variable?
The control group of the independant and dependant variable.
Whats the Octet Rule?
Its where Chemical Bonds take place because all atoms want to have a full outer energy shell/level.

Define Accuracy and Precision.
Accuracy depends on the instrument and Precision is based off the person who uses the instument.

instead of Jimmy nuetron think Chadwick Nuetron
were not gonna judge.
