Unformatted text preview: Sheet1 Page 1 Chapter 2 Atoms, Molecules and Ions Fundamental Chemical Laws A) Law of conservation of Mass (matter)-Mass is neither created or destroyed-Mass of reactanc = mass of product(s) B)Law of definite proportions-The elements in a given compound are always in a fixed proportion by mass-H2SO4 (Sulfuric acid)->2.1% Hydrogen, 65.3% Oxygen, 32.7% Sulfur by mass->These numbers will ALWAYS happen, no matter the amount tested C)Law of Multiple Proportions-If two elements X and Y combine to for more than one compound, the masses of Y that can combine with a given mass of X ->If we look at Iron (II) Chloride and Iron (III) Chloride->How many g of Cl will combine with 10g of Iron-->FE(II)Cl2, or FE(III)Cl3 D) Dalton's Atomic Theory 1. Each element is composed of small particles called atoms 2. Atoms of the same elements are identical, atoms of different elements are different and have different properties 3. The combination of atoms with each other results in chemical compounds. A given compound contains the same relative nu3....
