Question
The values are: 0.200g Na Water temp= 20.2C 5. Sodium reacts with water to produce H-(8) and sodium hydroxide in a highly exothermic reaction 2Na(s) + 2H2O(l) 2NaOH(aq) + H2(g) The heat from the reaction is sufficient to ignite the hydrogen gas. Assume this reaction was carried out under conditions that prevent H2 ignition. Using the same mass of Na(s) as was used for ZnO) in Part If your experiment, the same water temperature, and the same atmospheric pressure, determine the volume of H-(g) that you would generate, showing all of your calculations:Explanation / Answer
Na moles = mass/ atomic mass = 0.2/23 = 0.0087
H2 moles = Na moles/ 2 ( as per equation) = 0.0087/2 = 0.004348
T = 20.2 C = 20.2+273 = 293.2 K , P = 0.9893 atm
we use PV = nRT euqtion to find V
0.9893 x V = 0.004348 x 0.08206 x 293.2
V = 0.10574 L
