In the first cell, 42.51 mL of hydrogen gas were formed at the cathode.The temperature was 21.5C and the vapor pressure of water at this temperature is 19.240 torr. The Barometric pressure was 758.8 mm Hg and the height of water in the buret above the level of water in the beaker was 8.2 cm. Calculate: a. Partial Pressure of Hydrogen (H2) in buret (PH2 = Barometric – VP – Pheight) (The pressure due to the height of water still...

Calculate the amount of gas produced when collected by water displacement. Aluminum reacts with aqueous sodium hydroxide to produce hydrogen gas: 2Al(s) + 2NaOH(aq) + 6H2O(1) 2NaAl(OH)4(aq) + 3H2(g) In one experiment, a sample of Al reacts and the gas produced is collected by water displacement. The gas sample has a temperature of 23.00 °C, a volume of 860.0 mL, and a pressure of 747.0 mm Hg. Calculate the amount (in moles) of hydrogen gas produced in the reaction. The...
