Q

4 Principles of Dalton’s Atomic Theory

A

1.) Elements are made out of atoms
2.) Atoms of a given element are identical. If it were two different elements, their atoms are different
3.) Compounds are composed of atoms of more than 1 element
4.) A chemical reaction involves only the separation and rearrangement, not the creation nor destruction of atoms

46
Q

Signs that an object underwent chemical change

A

47
Q

What theory do these 2 sentences describe?:

A molecule will always stay in motion so long as it has energy depending on the temperature of an object

Changes in energy result in a phase change

A

Kinetic Molecular Theory

48
Q

What are the 3 key principles of the Kinetic Molecular Theory

A

1.) No energy gain or loss during molecule collision
2.) Molecules take up negligible space compared to its container
3.) Will always remain in linear motion until collision
