Answer 1

Elements are made up of extremely small particles called atoms.

Question 2

Part Two of Dalton’s Atomic Theory is..

Answer 2

Question 3

Part Three of Dalton’s Atomic Theory is..

Answer 3

Each chemical compound is unique and consists of a particular combination of specific types of atoms put together in a distinctive way.

Question 4

Part Four of Dalton’s Atomic Theory is..

Answer 4

Chemical reactions involve the reshuffling of the atoms in a compound to make new compounds. The new compounds are made from the same atoms which were present in the original compound.

Question 5

The Law of Definite Proportions, aka The Law of Constant Composition, states..

Answer 5

A chemical compound always has its component elements in a fixed ration by mass. This does not change based on its source or how it was formed.

Question 6

The Law of Multiple Proportions states..

Answer 6

When two elements combine with each other to form two or more compounds, the ratios of the masses of one element that combines with the fixed mass of the other are simple whole numbers.

Question 7

The Law of Conservation of Mass states..
