Gas Stoichiometry Practice EQ How can we know about something that we cannot see What sets gases apart Where do atoms go How do the gas laws explain the natural world Enduring Understanding All matter is made of tiny moving particles and because of these particles matter behaves in predictable ways The relationships between temperature pressure volume and amount of gases enable life to survive and flourish Even though gases cannot be seen their impact on the natural world is vital Science is a process Learning Targets Convert between Celsius and Kelvin temperature scales K C4273 Explain and calculate the volume and or miles using the relationship of Avogadrd s Law Solve problems using the idead Gas Law PVT Write volume ratios using the coefficients from a balanced chemical equation Volume of A Volume of Use the ideal gas law and gas stoichiometry to solve the following molsA Vol B Vol A Vel B grams Amols A Vols TEKS ZB Plan and implement investigative procedures including asking questions formidating a testable hypothesis BG Preform stoichiometric calculations including the determination of mass and gas volume relationships between reactants and products and percent yield 9A Describe and calculate the relations between volume pressure number of moles and temperature of an ideal gas as described by Boyle s Law Charles Law Avogadro s Law Dalton s Law of partial pressure and the ideal gas law Directions Solve the following problems Be sure to show all work for full credit For the following problems assume the reactions are taking place at a pressure of 1 0 atm and a temperature of 298 K Calcium carbonate decomposes at high temperatures to form carbon dioxide and calcium oxide CaCO CO 4 Cao 1 How many liters of calcium carbonate will decompose to form 3 45 liters of carbon dioxide 2 How many liters of calcium oxide will be formed from 9 6 liters of CaCO Ethylene burns in oxygen to form carbon dioxide and water vapor C H 30 2 CO2 2H O 3 How many liters of water can be formed if 1 25 liters of ethylene are consumed in this reaction How many liters of carbon dioxide will be produced from 3 1 liters of oxygen gas
