Chapter 2.1- 2.3 (pages 41-48) 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 elements by mass. Law of multiple proportions- When two elements form a series of compounds, the ratios of the masses of the second element that combine with 1 gram of the first element can always be reduced to small whole numbers Dalton?s Atomic Theory- -Each element is made up of atoms -The atoms of a given element are identical -Chemical compounds are formed when atoms of diff elements combine with each other -Chemical reactions involve reorganization of the atoms Dalton prepared first table of atomic masses

What Effect does Temperature on the Rate of Reaction? Introduction Temperature is nothing more than the average kinetic energy of a mass of atoms. This being said, the less kinetic energy present, the fewer collisions between the conglomeration of atoms, and thus the slower a reaction will progress (chemguide.co.uk). This idea is powered by the collision theory, allowing us to accurately hypothe- size what will happen based on the temperature of a solution. As we approach absolute zero (0o K), the rate of reaction asymptotically approaches zero, never reaching it ,since we can never thoeretically reach absolute zero, but getting infintesimally closer by a mesurable degree.

Periodic Properties of the Elements Review Questions 8.1 A periodic property is one that is predictable based on the element's position within the periodic table. 8.2 The relative size of the sodium and potassium ions is important to nerve signal transmission. The pumps and channels within cell membranes are so sensitive that they can distinguish between the sizes of these two ions and selectively allow only one or the other to pass. The movement of ions is the basis for the transmission of nerve signals in the brain and throughout the body. 8.3 The first attempt to organize the elements according to similarities in their properties was made by the German chemist Johann Dobereiner. He grouped elements into triads; three ele-
