Final answer:
To burn the acetylene gas, a certain amount of oxygen is needed. The number of oxygen tanks required can be calculated using the stoichiometry of the balanced chemical equation for the combustion reaction.
Step-by-step explanation:
The question is asking how many tanks of oxygen are required to burn the acetylene gas provided by an acetylene tank. To answer this question, we need to know the balanced chemical equation for the combustion reaction, which is:
2 C₂H₂ + 5O₂ → 4 CO₂ + 2 H₂O
From the equation, we can see that 2 moles of acetylene require 5 moles of oxygen. We can calculate the number of moles of acetylene gas in the tank by using the ideal gas equation:
n = PV / RT
Using the given values of temperature (0 °C) and pressure (1 atm), we can find the number of moles of acetylene gas. Then, we can use the stoichiometry of the balanced equation to calculate the moles of oxygen required. Finally, we can convert the moles of oxygen to the number of oxygen tanks required.
