Collecting Gas over Water Aluminum reacts with aqueous sodium hydroxide to produce hydrogen gas according to the following equation: 2Al(s) + 2NaOH(aq) + 6H2O(1)—>2NaAl(OH)4(aq) + 3H2(g) The product gas, H2, is collected over water at a temperature of 20 °C and a pressure of 756 mm Hg. If the wet H2 gas formed occupies a volume of 5.83 L, the number of moles of Al reacted was mol. The vapor pressure of water is 17.5 mm Hg at 20 °C.
Sodium metal reacts vigorously with water. A piece of sodium weighing 9.85 grams was added to a beaker containing 63.11 grams of water. During reaction, hydrogen gas was produced and bubbled from the solution. The final solution, containing sodium hydroxide, weighed 72.53 grams. How many grams of hydrogen gas were produced? If the density of hydrogen gas is 0.0813 g/L, what volume of hydrogen gas was produced?
Aluminum reacts with aqueous sodium hydroxide to produce hydrogen gas according to the following equation: 2Al(s) + 2NaOH(aq) + 6H20(1)—2NaAl(OH)4(aq) + 3H2(g) The product gas, H2, is collected over water at a temperature of 20 °C and a pressure of 746 mm Hg.
