american and french revolution essays

american and french revolution essays The American and French Revolutions were largely based on the same ideals and principals. With further investigation into the purpose and outcome of these two late eighteenth century revolutions many more comparisons and contrasts become apparent. These include how both revolutions were based on financial crisis as a result of prior wars and the philosophies of the period of enlightenment. Another, what was the real goal of each revolution? They differed quite substantially. After the respective revolutions ended the new state of the countries quite differed, one became a dictatorship while the other a democracy. These facts help give insight to how these two revolutions were related to one another. To understand these two revolutions in greater detail it is important to firstly understand their origins. During the eighteenth century philosophers such as John Locke (d. 1704), Jean-Jacque Rousseau (d.1778), Voltaire (d.1778), and Montesquieu (d.1755) perpetuated a period of enlightenment. This period is commonly noted for the intellectual movement in Western Europe that emphasized reason and science in philosophy and in the study of human culture and the natural world. Financial burden became one of the foundations for both of the revolutions. The thirteen colonies had been dealt responsibility for portions of the financial debt incurred by the British government during the French and Indian Wars (1754-1763), which merged with the Seven Years War (1756-1763). As a result of this large accumulation of debt the British Parliament introduced legislation to collect taxes in order to repay the debts. Acts such as the Tea Act, Stamp Act, and Sugar Act were introduced with great opposition from the colonies. Similarly, in 1774 King Louis XVI took the throne of France. With the assistance of his new controller general of finance he instituted a lassiez faire approach to economic growth. After much displease of Turgot ...

Predicting Formulas of Compounds with Polyatomic Ions

Predicting Formulas of Compounds with Polyatomic Ions Polyatomic ions are ions made up of more than one atomic element. This example problem demonstrates how to predict the molecular formulas of several compounds involving polyatomic ions. Polyatomic Ion Problem Predict the formulas of these compounds, which contain polyatomic ions:   barium hydroxideammonium phosphatepotassium sulfate Solution The formulas of compounds containing polyatomic ions are found in much the same way as formulas are found for monoatomic ions. Make sure you are familiar with the most common polyatomic ions. Here is a list of polyatomic ions to help you. Look at the locations of the elements on the Periodic Table. Atoms in the same column as each other (Group) tend to exhibit similar characteristics, including the number of electrons the elements would need to gain or lose to resemble the nearest noble gas atom. To determine common ionic compounds formed by elements, keep the following in mind: Group I ions (alkali metals) have 1 charges.Group 2 ions (alkaline earth metals) have 2 charges.Group 6 ions (nonmetals) have -2 charges.Group 7 ions (halides) have -1 charges.There is no simple way to predict the charges of the transition metals. Look on a table listing charges (valences) for possible values. For introductory and general chemistry courses, the 1, 2, and 3 charges are most often used. When you write the formula for an ionic compound, remember that the positive ion is always listed first. When there are two or more polyatomic ions in a formula, enclose the polyatomic ion in parentheses.Write down the information you have for the charges of the component ions and balance them to answer the problem.   Barium has a 2 charge and hydroxide has a -1 charge, therefore1 Ba2 ion is required to balance 2 OH- ionsAmmonium has a 1 charge and phosphate has a -3 charge, therefore3 NH4 ions are required to balance 1 PO43- ionPotassium has a 1 charge and sulfate has a -2 charge, therefore2 K ions are required to balance 1 SO42- ion Answer Ba(OH)2(NH4)3PO4K2SO4 The charges listed above for atoms within groups are the common charges, but you should be aware that the elements sometimes take on different charges. See the table of the valences of the elements for a list of the charges that the elements have been known to assume. For example, carbon commonly assumes either a 4 or -4 oxidation state, while copper usually has as 1 or 2 oxidation state.
