|
Heterogeneous |
Not the same throughout (oil and water, for example). |
|
|
Homogeneous |

|
|
Law of conservation of mass |
Mass is neither created or destroyed. Substances change but the total amount of matter doesn't. Mass of reactants = mass of products |
|
|
Law of definite proportions |
Different samples of a pure substance always contain the same proportion of elements. Elements do not combine in random proportions. |
|
|
Law of multiple proportions |
If two elements combine in different ways to form different substances, the mass ratios are small whole-number multiples of each other (in other words, it's possible for the same elements to combine in different ratios). |
|
|
Isotope behavior |
Isotopes behave almost identically in chemical reactions to their regular counterpart. It is electrons that determine chemical reactions. |
|
