Used in welding metals, the reaction of acetylene with oxygen hasdeltaH = -1256.2 kJ
C2H2 (g) + 5/2 O2 (g) ---> H2O (g) + 2CO2 (g) deltaH = -1256.2kJ
How much PV work is done (in kilojoules) and what is the value ofdeltaE (in kilojoules) for the reaction of 6.50g of acetylene atatmospheric pressure if the volume change is -2.80 L?

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)â4CO2(g)+2H2O(g) You have a 5.50 L gas tank and a 3.50 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 155 atm , to what pressure should you fill the acetylene tank to ensure that you run out of each gas at the same time?

Imagine that you have a 7.00 L gas tank and a 2.50 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 115 atm , to what pressure should you fill the acetylene tank to ensure that you run out of each gas at the same time? Assume ideal behavior for all gases.
