Lab #4: Aqueous Reactions Introduction: In this experiment we studied the two different types of aqueous chemical reactions‚ double replacement and single replacement. In a double replacement reaction one or both of the products is an insoluble ionic compound or otherwise known as a precipitate; or a non-electrolyte; or a gas. In a single replacement reaction there is typically a metal and an ionic compound consisting of a metal cation and a non-meatl anion. Singel replacement ractions occur when

6/25/2014 Philosophy 201 Reaction to Kant Kant Kant first draws close to differentiating between a moral choice and a prudent choice. A prudent choice is a choice used in good judgment and is rational. Kant has no interest in morality being rational. A law is a law and thou shall obey it. The moral law is absolute. Thou shall not lie‚ means exactly what it says‚ thou shall not lie. No ifs‚ ands or buts about it. There is no reason why a person should lie because it is our duty as moral

Anthony Young Partner: Nick Dale TA: Alekhya 6/15/15 The SN2 Reaction: Factors Affecting SN2 Reaction. Introduction In the substitution reactions‚ the leaving group from the substrate is replaced with the nucleophile. Because of the nucleophile it is called nucleophilic substitution. The lone pair of electrons‚ present on the nucleophile is used to create a new bond with the carbon atom‚ from which the leaving group was separated. There are two different mechanisms of nucleophilic substitution: SN1

Observing the situation‚ we can say that every bee in the colony has a specific function or role. That is how bees‚ even though small and simple‚ can be strong and smart. They have order and functionalism to build and maintain their colony. But can humans‚ being more complex and free-minded than bees‚ be subjected to complete order? The Verichip is a microchip that can be implanted under one’s skin. Each chip is unique; each has a verification number used for identification purposes. It can be used to

Social Studies Julie Shapiro “Crito” Reaction 10/14/12 The great Athenian philosopher Socrates believed in justice and overall fairness regarding the law. If a crime were committed‚ Socrates would rather take the punishment instead of seeking revenge. His morals consisted of accepting the scandal he had executed and not take vengeance. This differs from Hammurabi’s eye for an eye method. Hammurabi followed a path of abase payback and doing onto others what had been done to you. Socrates

Coralde Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines Results and Discussion A combustion reaction is a reaction that liberates heat and light. Magnesium is a stable element and reacts violently with evolution of much heat and light. The reason the magnesium burned in carbon dioxide was because it combined with the oxygen in the CO2 leaving elemental carbon behind. CO2(g) C(S) + O2(g)
