States of Matter
This theory is based on the idea that particles of matter are always in motion.
The Kinetic Molecular Theory
A substance that reacts with metals to release hydrogen
Acids
Molecules that are composed of carbon, hydrogen, and oxygen atoms in a 1:2:1 ratio, and provide nutrients to the cells of living things.
Carbohydrates
If a number contains no zeros, it is significant
Which number is significant?
a. 017 b. 44 c. 708
b. 44
