The Synthesis of hydrogen chloride is written H2+Cl2==>2HCl. 3L of hydrogen are used and all gasses are at STP. The volume of HCL produced in the reaction would be _______ L.
would the answer be 5.96?
Three liters of H2 yields six liters of HCl, from the balanced equation. I don't know how you got 5.96.
From the balanced equation, each liter of H2 gives 2 liters of HCl. I suspect you turned the volume of H2 to moles, then moles of HCl, then back to volume of HCl. No need to do that: All gasses have the same number of moles in the same volume at the same pressure, temp.
oooh- so i wasted time doing all that- Thanks!!
No problem! It's always important to understand the concept behind the problem and work smarter, not harder. In this case, you can use the stoichiometry of the balanced equation to determine the volume of HCl directly.
According to the balanced equation, 1 mole of H2 reacts to produce 2 moles of HCl. Since the volume of gases at STP is directly proportional to the number of moles, we can say that 1 liter of H2 will react to produce 2 liters of HCl.
Therefore, if you have 3 liters of H2, you can simply multiply it by the stoichiometric ratio:
3 liters H2 * (2 liters HCl / 1 liter H2) = 6 liters HCl
So, the correct answer is indeed 6 liters of HCl.
