Answer:
A. 6 water molecules, hydrogen is limiting.
Explanation:
For a molecule of water, you need 2 hydrogen atoms and 1 oxygen atom. Therefore, if there is 6 molecules of hydrogen and 6 molecules of oxygen, there are 12 atoms of hydrogen and 12 atoms of oxygen. You need 2 of hydrogen so you will divide 12 by 2. 12-2=6. You need only 1 atom of oxygen so it will stay as 12. The limiting reactant is hydrogen because there are only 6 while there are 6 atoms of oxygen remaining. There will only be 6 water molecules formed due to the insufficient amount of hydrogen.
Answer:
1.15 moles H₂
Explanation:
To find the moles of H₂ gas, you need to use the Ideal Gas Law equation. The equation looks like this:
PV = nRT
In this equation,
-----> P = pressure (atm)
-----> V = volume (L)
-----> n = moles
-----> R = Ideal Gas Constant (0.08206 L*atm/mol*K)
-----> T = temperature (K)
Before you can plug the given values into the equation and simplify, you need to convert Celsius to Kelvin.
P = 0.923 atm R = 0.08206 L*atm/mol*K
V = 29.6 L T = 17.0 °C + 273.15 = 290.15 K
n = ? moles
PV = nRT
(0.923 atm)(29.6 L) = n(0.08206 L*atm/mol*K)(290.15 K)
27.3208 = n(23.809709)
1.15 = n
