2. What is chemistry? Chemistry is The study of matter

What is matter? Anything that has mass and takes up space. Is it matter? You? Yes Air? Yes An idea?

No

Anger? No Religion?

No

A perfect vacuum?

Can you hit the bull's-eye? Three targets with three arrows each to shoot.

How do they compare?

Both accurate and precise

Precise but not accurate

Neither accurate nor precise

Can you define accuracy and precision? bullseye consistent 10. The big question: What is everything made out of?
