Chemistry 1.1

Why is chemistry known as "the central science"?

• It plays vital roles in all other scientific disciplines

• The other sciences do not use chemistry at all

• Chemistry is not known as "central science"

What is a hypothesis?

• A basic statement established by experiment or observation

• An educated guess that predicts the outcome of your experiment

• a comprehensive explanation that is supported by facts gathered over time.

• Rules for how nature will behave under certain conditions, frequently written as an equation.

• A statement that is not scientifically provable

What is a fact?

• A basic statement established by experiment or observation

• An educated guess that predicts the outcome of your experiment

What is a law?

• A basic statement established by experiment or observation

• objects are large enough to be sensed directly by human sight or touch

• objects are too small to be seen even with the most advanced microscopes and may only be pictured in the mind.

• the specialized language used to represent components of the macroscopic and microscopic domains.
