Properties of Chemical Reactions Ms. Whitty‚ Science 10 Fiona Adams‚ November 1st‚ 2012 Introduction Chemical reactions are a part of our daily lives‚ from rusting metal to making bread to leaves changing colour in the fall. A chemical reaction is the process that occurs when two or more substances combine to produce a chemical change. When a chemical reaction takes place‚ the change is indicated by one or more qualitative properties. The colour or odor could change‚ gas could be produced

counterparts. Often denied access to proper education‚ goods‚ property and freedom‚ colored people were continuously exploited as property themselves and unwillingly later became slaves to the elite classes. As a result‚ the notion of a slave owning property‚ of property owning property‚ quickly became rejected as plausible. Afterall‚ slaves were constantly “working from sunup to sundown” (234) and lacked the funds and skills necessary to acquire property. However‚ author Philip D. Morgan dismisses this stereotypical

Physical and Chemical Properties Purpose: The Physical and Chemical Properties lab provides the opportunity to investigate the physical and chemical properties of pure chemical substances and analyze the experiment results. Procedure: In the beginning of the experiment‚ I filled two 24-well plates half way with the given chemicals and sucked up these chemicals into their labeled pipets for later use. Following this‚ I performed a number of steps on each of the four test tubes and recorded observations

List of the First 20 Elements and their Physical Properties Atomic Radii (pm) of the First 20 Elements: - Atomic radii decreases when moving down a period‚ as the number of protons increases‚ which thence increases the effective nuclear charge. - Atomic radii increases when moving down a group‚ as the number of shells increases‚ which thence increases shielding. - The downward-sloping pattern on the above graph shows the decrease in atomic radii down a period‚ and the sudden jumps

The Periodic Properties of Atoms The Periodic Table: In the 1870’s‚ the Russian chemist Mendeleev developed the periodic table‚ based upon the relationship between the atomic weights of the elements and their chemical properties. As one ascends from lightest to heaviest elements‚ there is a periodic recurrence of chemical properties. For example‚ the elements with atomic numbers 2‚ 10‚ 18‚ 36‚ 54‚ and 86 all are chemically inert (the noble gases)‚ while those with atomic numbers one greater 3‚ 11
