Persuasive Essay By: Marty Wilson You think hockey headshots aren’t bad? Tell that to the family of Russian forward Dmitri Uchaykin who died after receiving a hit to the head during a KVL game. My stance is clear‚ stop headshots in hockey. The amounts of injuries are insane from headshots on the ice. James Neal took an elbow to the head from Micheal Del Zotto during Pittsburgh’s game with the New York on Friday night. Neal was an outstanding

Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation

Lab Report Electrical Conductivity Introduction There are some substances that are capable of conducting electricity‚ and the reason they conduct electricity is because of the type of compound the substance is. Electrolytes or any ionic compound conduct electricity and nonelectrolytes do not conduct electricity. An Ionic compound is formed from the electrical attraction between anions and cations‚ typically a metal with a non-metal‚ except hydrogen. When an ionic compound forms‚ the anion

These tests helps us to determine the properties of the drilling fluid and so what can be done to make the mud perform more efficiently. For the density and rheological properties a mud balance is used to test density i.e. fill the cup so that a little
