Problem 62E

Problem 62E

Further Applications of the Ideal-Gas Equation (Section)

Acetylene gas, C2H2(g), can be prepared by the reaction of calcium carbide with water:

CaC2(s) + 2 H2O(l)→Ca(OH)2(aq) + C2H2(g)

Calculate the volume of C2H2 that is collected over water at 23 °C by reaction of 1.524 g of CaC2 if the total pressure of the gas is 753 torr. (The vapor pressure of water is tabulated in Appendix B.)

Economics Chapter 1 Welcome to Economics Topics 1. The world of economics 2. What is economic Why is it important 3. Division of labor 4. Why study Economics 5. Microeconomics and Macroeconomics 6. Theorizing in Economics The world of Economics - Decision making - Processing information fast and accurate - Understanding market behavior What is Economic Why is it important - Defining Economics as the study of how human make decision in the face of scarcity - Scarcity - Resource scarcity - Virtually infinite human wants - Food, shelter, clothing, transportation, entertainment is all scarce - Scarcity is evident in hunger, homelessness, lack of critical healthcare - We cannot have everything we want - How do we solve the problems of scarcity - Family must decide between a car and a vacation - Town must choose between police station or a new school - Nations mast chose between war and protecting the environment - Resources are insufficient to buy everything - So why not just produce everything we need Division of Labor - Modern economics are characterized by division and specialization of labor - Divide production into several small tasks - Allot workers to perform individual tasks - Modern businesses build on specialization  Restaurants  University  Shoe factory  Hospitals - Why Specialize  Focus on comparative advantage  Efficient (quicker production) and higher quality  Economics of scale (increase in production reduces average cost per unit)  Trade and procure other goods and services Why study Economics - Virtually every problem has an economic dimension - Global warming, world poverty, armed conflicts - Understand budget, regulation, law in order to be a good economic citizen - Become a well wounded thinker - Question the validity of statements (such as made by politicians) Microeconomics and Macroeconomics - Microeconomics – Focus on the individual agent (consumer choice, profit maximization, labor­leisure choice, human capital decisions) - Macroeconomics – Focus on the economy (growth, inflation, unemployment rate, fiscal policy, monetary policy) Theorizing in Economics - Theory – Simplified representation of how two or more variables interact with each other - Break­down real world to understand essentials - Simple enough to understand - Complex enough to capture essential feature - Ex: circular flow diagram
