Pangaea is scientifically known as the original whole mass of land that eventually was divided into separate mass entities called continents as a result to natural phenomena like earthquakes. This is more explained inthe continental drift theory. After rigorous collection of evidences, scientists noticed that fossilized plants and animals of the same species, also with the coastlines match on different continents. The answers are the first and second choices (A and B).
Given: <span> 2.1 moles of chlorine gas (Cl2) at standard temperature and pressure (STP) Required: volume of CL2 Solution: Use the ideal gas law PV = nRT V = nRT/P V = (2.1 moles Cl2) (0.08203 L - atm / mol - K) (273K) / (1 atm) V = 47 L</span>
