Problem 12E

Consider the conversion of compound A into compound B: AB. For both compounds A and B, . (a) Sketch an enthalpy diagram for the reaction that is analogous to Figure 5.23. (b) Suppose the overall reaction is exothermic. What can you conclude? [Section 5.7]

Step-by-Step Solution:
Step 1 of 3

 Countries of Europe o Germany  82 million people  Initially was made up several tribes, royal families  Unified late 1800s early 1900s  Was divided after WWII  West Germany = part of Europe, democratic  East Germany = USSR, Communist  Contains 16 states  Highly urbanized  89% of the population  A leader in Europe : manufactoring/economic stability  Largest economy of Europe  Has the Autobahn (interstate system) o France  64 million people  Oldest state in europe  Urban  Paris 2.2 million people  Contains the highest Mountain in Europe  Mount Blanc  Huge in agriculture (biggest producer in Europe)  Cattle, grapes, cheese  Known for  Rich food  Architecture  Art o Great Britain  UK  62.7 Million People  Regions:  England, Scotland, Wales, Northern Ireland  Surrounded by water:  North Sea, English Channel, and the Atlantic Ocean  The US's strongest ally  National Dish:  Chicken Tikka Masala  Prominent Religion  Protestant o Ireland  Highest growing economy in the EU  Uses the Euro  Gained independence form the UK in 1921  Conflict between the Catholics and Protestants  Irish Republican Army (IRA)  English and Gaelic are the national languages  Strong Irish Influence in America  New York  Boston  Chicago o Italy  60.5 million people  Major states or regions  Tuscany, Milan, Venice, Piedmont  Rich urbanized North  Poor rural South  Sicily is very poor and underdeveloped  Origin of La Cosa Nostra (Sicilian Mafia)  Milan-Turin-Genoa Triangle  Heavy manufacturing  Milan is the largest city in Italy o "Rock" of Gibraltar  2.6 sq mile area (peninsula Iberian)  South Spain  Owned by Britain  Surrendered by Spain in 1713 (via the War of the Spanish Succession)  One of the most densely populated areas in the world  12,840 people per square mile  Official language is English  Important militarily and economically  Access to the Mediterranean sea from the Atlantic  Recent events in Ukraine o Major divisions after the Cold War o Country divided politically  East = Pro Russia  West = Pro Europe o Russia needs access to the ocean and resources  Military and economic factor… o Babushkas of Chernobyl  Self-settlers  Wildlife  Returning in force  Invisible enemy  Women who were children during Stalin's reign.  Starvation  Stalin burned down cities and towns along with all of the agriculture.  Lived through WWII with the Nazi's.  Concentration camps or forced labor.  Relationships do not equal causation  The world health organization says 4000 deaths while green peace says 10000 deaths.  The women are out living the men because the men are drinking and smoking, across the world it is more accepted for a man to drink and smoke than it is for a woman.  In that case you have higher numbers of men drinking and smoking and dying from that instead of the radiation poisoning.  The town was built around Chernobyl.  The people who were relocated seem to be dying sooner than the ones who came back. o Russia is the biggest country by land area. o You can see Alaska from Russia, only 4km between the two. o Physical Geography  SW Russia desert  Main area of settlement near Moscow  Cannot connect to any waterways.  Caspian sea o 4 regions  Russian core  Majority of the population  Siberia  Freezing  Where people would be exiled  Eastern Frontier  Desert section  Separation between Siberia and Frontier is climate and culture  Far East  Not many settlements  Hard to navigate the land o Approximately 75% of Russia is Siberia has far as land area o A majority of the population lives in the Russian Core and the Eastern Frontier o Physical Russian Geography  Russian Plain  West of the Ural Mountains; Moscow (core of Russia)  Ural Mountains (2000 miles long)  Low relief mountain chain separating East/West Russia  Western Siberia (constant elevation)  Flat plains and forests  Central Siberia  Moderate mountains; very cold (Artic Circle)  Eastern Highlands (Mostly the Yakutski Basin)  One of the most remote places on earth o Climate  SW desert  Russian Core humid continental (northern Midwest into Canada)  Majority is subarctic. (FREEZING)  Tundra only has a few centimeters a year that is thawed for a limited amount of time. o Interesting facts about Russia  Continentally has a huge impact on Russia's climate  Similar to the upper Mid-west and Canada  Economy is rising  It depends heavily on oil  Becoming increasingly more "modern" and "western"  Red square  A city square block where the government is housed  Misconceptions  Not called red square because it is called a communist country  Not because the buildings are red  It is because the language has evolved.  Used to be the slums until the 1400s o The Soviet Union  U.S.S.R.
