Document Summary

Chapter 1 & 2 chemistry: chemical foundations: metric system = si units. Mass : gram length : meter volume : liter. Multiplication/ division = take the numbers of smallest. Boiling points: c = 100, f = 212, k = 373. 15. Matter = anything that has mass and occupies space. An atom is the smallest particle of an element that still has all the properties of the element: fundamental laws. Law of conservation of mass- mass is neither created nor destroyed. Law of definite proportion a given compound always contains exactly the same proportion of the elements by mass. Ratio of atoms in a compound always small, whole number, same proportion of elements by mass. You divide the top number by the bottom, and the smaller number becomes 1 and the top number you round up. Co2 same ration every time: dalton"s atomic theory.
