The gas welding torch is fueled by two tanks, one containing acetylene (C2H2) and the other pure oxygen (O2). The very hot flame of the torch is produced as acetylene burns, 2C2H2 + 5O2 → 4CO2 + 2H2O According to this equation, how many liters of oxygen are required to burn 8.00 L of acetylene?_____ L of O2
Acetylene torches are used for welding. These torches use a mixture of acetylene gas, C2H2, and oxygen gas, O2 to produce the following combustion reaction: 2C2H2(g)+5O2(g)→4CO2(g)+2H2O(g) Imagine that you have a 7.00 L gas tank and a 3.00 L gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch. If you fill the larger tank with oxygen to a pressure of 145 atm , to what pressure...
